ANCAL is intended for use on AIPS VLBI multisource data sets. The T sys's and gain curves are supplied by the user in a free-format text file. The modified CL table may be applied to the data using standard calibration routines such as LISTR, CALIB or SPLIT. If baseline dependent corrections (BASELINE cards) are given they will be written into a BL table. Only one set of baseline corrections for all IFs and polarizations and sources can be given. If multiple subarrays are contained in the data, one execution of ANCAL must be made for each subarray. As of 15APR93 it is possible to calibrate dual polarization data in one pass of ANCAL. Adverbs: INNAME.....Input UV file name (name). Standard defaults. INCLASS....Input UV file name (class). Standard defaults. INSEQ......Input UV file name (seq. #). 0 => highest. INDISK.....Disk drive # of input UV file. 0 => any. CALIN......Calibration text file. Contains data for 1 polarization. GAINVER....The CL table version number which is to be updated. Don't modify CL table version 1, use TACOP to make a higher numbered copy. -1 will cause the TY to be created and filled, but will not update the CL table. BLVER......Version number of the baseline based calibration (BL) table to write. (Only if BASELINE cards). 0 => highest. SELBAND....Bandwidth of data to be selected. If more than one IF is present SELBAND is the width of the first IF required. Units = kHz. SELFREQ....Frequency of data to be selected. If more than one IF is present SELFREQ is the frequency of the first IF required. Units = MHz. FREQID.....Frequency identifier to select (you may determine which is applicable from the OPTYPE='SCAN' listing produced by LISTR). If either SELBAND or SELFREQ are set their values overide that of FREQID, however setting SELBAND and SELFREQ may result in an ambiguity, in which case the task will request that you use FREQID. SUBARRAY...The subarray to calibrate, if there is more than one subarray active at the same labeled time then it is best to run ANCAL once for each subarray. BADDISK....A list of disks on which scratch files are not to be placed. This will not affect the output file. ---------------------------------------------------------------- ANCAL : Computes visibility amplitude corrections using T sys / T ant tables. DOCUMENTOR : J.M. Benson, NRAO/CV RELATED TASKS : Applies to VLBI data sets (VLBIN, UVLOD). Needs application by CALIB, SPLIT etc. PURPOSE ANCAL determines T sys and antenna gain corrections to raw VLBI cross-correlation coefficients. ANCAL reads a user prepared text table that contains lists of T sys's, gain curves, VLBI b-factors, source fluxes and T ants. The output of ANCAL is a modified CL table containing the amplitude calibration information. This table can be applied to the data using standard calibration routines such as LISTR, CALIB or SPLIT. COMMENTS CALIN: The user must create a table from which ANCAL reads T sys's and gain curves. The table can be manually entered into a file using a text editor. The format of the table is nearly identical to that used by the Caltech VLBI program CAL. A table which can be read by CAL is acceptable to ANCAL. Examples: CALIN='disk$res:[username]cal.dat' (VMS) CALIN='myarea:cal.dat' (Unix) where MYAREA is an environment variable set before starting AIPS: %setenv MYAREA /mnt/username The are five type of "groups" in the ANCAL calibration table. A "group" may be more than one line and is delimited by an "/". Up to 200 characters per line are allowed. The delimiter "/" must be separated from the preceeding character by at least one blank. The group format is essentially free; there are no column requirements. ANCAL will evaluate arithmetic expressions contained within parentheses. The accepted operators are +, -, * and /. Example, FLUX=(1.0-2.5*2.2+3.1/3.3). Any characters to the right of "!" are disregarded, thus comments may be included anywhere in the text. A description of the calibration groups follows: ================================================================ 1) The control group. A list of source names and flux densities are entered, as well as the default value of the VLBI b-factor, the first and last IFs to calibrate and the polarization number (1=R, 2=L). Although as of 15APR93 the IF range and polarization number may be overridden by means of the INDEX or ALLCHAN keywords. The b-factor should be set explicitly in the cal. file using keyword BDEFAULT. THE CONTROL GROUP MUST BE THE FIRST GROUP IN THE CALIN file. Note: at least one source name must be given. Example : BIF=2 EIF=4 POLNO=1 ! from this file extract TSYS for ! IF numbers 2 to 4, right ! circ. poln. If the INDEX keyword ! is present in the TSYS section ! then BIF, EIF, POLNO are ignored. SOURCE='0235+164','DA193','3C120' FLUX=2.4,4.6,2.6 BDEFAULT=2.5 / Example (just specify flux for one source) : SOURCE='3CXYZ' FLUX=4.1 BDEFAULT=2.5 / ! comments comments Note: If calibration data is only available for one IF then IFNO may be used in place of BIF and EIF; IFNO=n is equivalent to BIF=n EIF=n. ================================================================ 2) The baseline group. The baseline group is used to specify special b-factors for specific baselines. You must include the word BASELINE and two station names. You may include more than one baseline group. Example : BASELINE NRAO OVRO B=2.25 / BASELINE GRAS IOWA B=3.15 / If any of these groups are given a BL table will be written. This table must be applied in order for these corrections to be made. Only a single set of baseline dependent factors (all IFs and Polarizations and sources) may be given. ================================================================ 3) The system temperature group. The Tsys group identifies a station with a list of Tsys entries which follow it. The parameter FT is a multiplier applied to the Tsys's. TIMEOFF gives the correction in seconds to be added to the time to convert it to IAT - this may be set to zero if the data comes from a MkIII correlator, the NRAO MkII correlator or the VLBA correlator since the time system now used for these data within AIPS is UTC. The Tsys list must contain 2 + NIF values per entry, where NIF is the number of (IFs * polzns) to be calibrated, i.e. the number of video-converters (or BBC's in VLBA parlance) The order of the Tsys list is as follows (free format): day number of the year, time of T sys measurement (IAT) HH:MM:SS, and NIF Tsys values (degrees K). Each value must be separated by a blank from the others and a line must be less than 80 characters long. The Tsys table may have more than one day's worth of entries. Missing days in the visibility data need not be included in the Tsys table. Note: the format of a T sys entry where there is more than 1 IF is close to, but not identical to the format of T sys records in a machine readable MkIII field system log. Values from the field system log may be pasted into the ANCAL input file after preprocessing to change the format of the date and time and to remove the commas separating the T sys values. The preprocessing may be done using a programmable editor such as emacs or (on Unix systems) using a simple awk script. As of 15APR93 AIPS there are three new keywords allowable in the Tsys group, these enable a more general method of dealing with multi-IF and polarization data. The three keywords are INDEX, ALLCHAN, BOTHSIDE - their use is described below: If the INDEX keyword is present then it specifies the polzn and freq. order of the TSYS data, R or L is RHC/LHC the digit(s) represent freq order (increasing frequency). Up to 28 entries may be present. If the INDEX keyword is being used and a column, or set of columns, in the TSYS/TANT groups are to be ignored, then the user should insert an X as the first character of the relevant index, i.e. INDEX = 'R2', 'L1', 'L2', 'X3', 'R1' This enables the user to specify the order of the Tsys data randomly, so that if, for instance, it is not in frequency order then the index keyword can reflect that and the data will be sorted as it is read in. The ALLCHAN parameter is used when a multi-IF observation is being calibrated but only one Tsys measurement is available. In this case the Tsys list contains only 3 entries (day, time, Tsys value) but the Tsys value is to be applied to all IF's for the polarization specified by the POLNO keyword in the control group. It is meaningless to specify an INDEX for a Tsys group if ALLCHAN is also specified and this will be treated as an error. In the case where the data are stored with upper and lower sidebands as seperate AIPS IF's but there is only one Tsys value for each pair then the user should use the parameter BOTHSIDE. In this case the number of Tsys columns will be NIF/2. ALLCHAN and BOTHSIDE cannot both be true simultaneously. Example(1) : TSYS NRAO FT=1.0 TIMEOFF=23.0 / 289 01:02 45.55 ! 1 IF/1 polzn 289 01:31 46.55 289 02:01 47.34 289 03:05 48.90 290 01:01 44.40 290 05:01 48.64 ! can have more than one 290 05:59 48.65 / ! entry per line (above) Example(2) : the use of the INDEX/ALLCHAN parameters TSYS NRAO FT=1.0 INDEX='R2','L2','R1','L1' / 289 01:02 45.55 47.32 46.40 51.0 ! 4 TSys numbers are RHC 289 01:31 46.55 48.27 47.32 49.9 ! high freq, LHC high freq, 289 02:01 45.70 49.00 47.21 50.5 ! RHC low freq, LHC low freq / TSYS VLA FT=1.0 ALLCHAN / 289 01:05 34.0 ! One Tsys number for all IF's 289 01:32 34.5 289 02:00 37.0 / ================================================================ 4) The gain group. Several gain curves are built into ANCAL. The gain group indicates which gain curve is desired and allows the user to supply gain coefficients. Currently (15APR93) the gain curves in ANCAL are : EQUAT (hour angle), ALTAZ (zenith angle), ELEV (elevation angle), GCNRAO (NRAO 140' gain curve), GCAREC (Arecibo line feed, zenith angle). GCAREC is the Arecibo gain curve at 18 cm . The NRAO 140ft gain curve is the seven or ten term spherical harmonic expression whose coefficients are distributed with the 140ft observing logs. A 140ft example is shown below. Up to six coefficients are supplied via POLY. The polynomial variable may be offset by using OFFSET and an antenna sensitivity constant DPFU (degrees per flux unit) must be entered. The gain curve polynomial is evaluated at the appropriate hour angle, zenith angle or elevation and multiplied by DPFU. In those cases where observatories supply non-normalized gain curves, DPFU must be adjusted accordingly. As of 15APR93 it is possible to calibrate dual polarization data in one run rather than having to run ANCAL twice with POLNO = 1 and 2. If the data being calibrated are dual polarization, and the INDEX or ALLCHAN keywords are being used then the user may supply two values of DPFU (i.e. DPFU = 0.165, 0.175 or DPFU = (8.0*0.85), (8.0*0.95)). The first value of DPFU refers to the RHC channel, the second to the LHC channel. If either is zero then they will both be set to the non-zero value. The same logical rule applies to the OFFSET keyword. Examples : GAIN NRAO GCNRAO DPFU=(1.0/1.93) A00=0.4638 A10=0.0690 A11o=0.0012 A11e=0.0792 A20=-0.0143 A21o=-0.0054 A21e=-0.0095 / ! could also include the A22o, A22e and A30 terms for the ! 140ft. GAIN OVRO ALTAZ DPFU=(0.21*2.05) ! comments POLY= 0.7974, 1.298E-2, -2.510E-4, 1.298E-6 / GAIN GRAS ALTAZ DPFU=0.092 OFFSET=-4.0 POLY= 0.9158, 0.004752, -7.98E-5, 3.4E-7 / GAIN HSTK ELEV DPFU=0.165 POLY= 0.911, 3.6E-3, 2.0E-6, -1.3E-6, 1.0E-8 / GAIN ARECIBO GCAREC DPFU=(8.0*0.95) / GAIN ONSALA EQUAT DPFU=(0.0926/1.13) / ================================================================ 5) The antenna temperature group. Antenna gains may be tracked by measured antenna temperatures. The TANT group is used to identify the station whose T ant list follows. The formats are the same as the TSYS group and list but there is only one value of Tant for all IFs (ie. each entry should contain a daynumber, a time and one Tant number). The special keywords INDEX, BOTHSIDE and ALLCHAN are not used. ================================================================ 6) To calibrate the VLA for VLBI, consult the explanatory memo appended to the end of your VLA calibration file. ================================================================ QUANTITATIVE DESCRIPTION: ANCAL calculates the antenna gain calibration values in this manner (for the k-th antenna) : GA-k = BDEFAULT * Tsys-k / ( DPFU-k * POLY-k ). For stations with measured antenna temperatures, Tant-k, : GA-k = BDEFAULT * Tsys-k * FLUX / Tant-k. ANCAL converts the input visibility amplitudes into correlated flux densities (jk baseline) : VIS-jk (Jy) = (BFAC-jk/BDEFAULT)*SQRT(GA-j * GA-k)*VIS-jk, where BFAC-jk is the optional baseline based VLB b-factor. The AIPS weights with each output visibility record are scaled proportionally to the estimated antenna sensitivities : output vis. weight-jk (proportional to time) = (input vis. weight-jk) * 2 * bandwidth * DPFU-j * DPFU-k --------------------------------------------------------- . b-factor * Tsys-j * Tsys-k ================================================================ A full example: BIF=1 EIF=4 POLNO=1 ! redundant because use INDEX SOURCE='3C345','OQ208' FLUX = 10, 1.849 ! 3C345 is wild guess. !

This section can be read by ANCAL (AIPS) or CAL (CIT). ! System temperatures are given in channel order left to right. ! A system temperature of 999.9 indicates a bad data point. ! Times are in UT so give IAT-UTC to ANCAL with parameter TIMEOFF. ! Negative sky frequency indicates net lower sideband; positive indicates upper. ! Scan headings are Station id, Project code, Source/Qualifier, and scan time range. ! Basically speaking, scan changes inside loops are ignored. !
