UVPRT differs from PRTUV in that calibration information can be applied before printing. If calibration information is to be applied the data must be in TB sort order. UVPRT also displays seconds of time in floating point where possible and does not display a "visibility number" since that is not meaningful under the calibration package. UVPRT no longer does anything special for holography data; see UVHOL. 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. SOURCES....List of sources to be printed. ' '=> all; if any starts with a '-' then all except ANY source named. QUAL.......Qualifier of source to be printed. -1 => all. CALCODE....Calibrator code of sources to print. ' '=> all. STOKES.....The desired Stokes type of the printed data: 'I','Q','U','V','RR','LL' select a single Stokes or correlator, 'IV', 'QU', 'HALF' select 2 Stokes or correlators, 'IQUV' selects 4 Stokes, else 'FULL' is used for 4 correlators. 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. For data which contain multiple bandwidths/frequencies the task will insist that some form of selection be made by frequency or bandwidth. 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 that case, the task will request that you use FREQID. If all SELBAND, SELFREQ and FREQID are not specified (.le. 0) then all FQ ids will be selected. TIMERANG...Time range of the data to be printed. In order: Start day, hour, min. sec, end day, hour, min. sec. Days relative to reference date. ANTENNAS...A list of the antennas to print. If any number is negative then all antennas listed are NOT desired and all others are. All 0 => list all. BASELINE...Baselines are specified using BASELINE. E.g. for baselines 1-6,1-8, 2-6 and 2-8, use ANTENNAS=1,2; BASELINE=6,8. UVRANGE....Range of projected spacings to be printed in 1000's of wavelengths. 0 => 1, 1.E10 SUBARRAY...Subarray number to print. 0 => 1. CHANNEL....Spectral line channel number. 0 => 1. BIF........IF number to print. 0 => 1 DOCALIB....If true (>0), calibrate the data using information in the specified Cal (CL) table for multi-source or SN table for single-source data. Also calibrate the weights unless DOCALIB > 99 (use this for old non-physical weights). GAINUSE....Version number of the Cal. table to apply to the data if DOCALIB=1. Refers to a CL table for multi-source data or an SN table for single source. 0 => highest. DOPOL......If > 0 then correct data for instrumental polarization as represented in the AN or PD table. This correction is only useful if PCAL has been run or feed polarization parameters have been otherwise obtained. See HELP DOPOL for available correction modes: 1 is normal, 2 and 3 are for VLBI. 1-3 use a PD table if available; 6, 7, 8 are the same but use the AN (continuum solution) even if a PD table is present. PDVER......PD table to apply if PCAL was run with SPECTRAL true and 0 < DOPOL < 6. <= 0 => highest. BLVER......Version number of the baseline based calibration (BL) table to apply. <0 => apply no BL table, 0 => highest. FLAGVER....Specifies the version of the flagging table to be applied. 0 => highest numbered table. <0 => no flagging to be applied. DOBAND.....(multisource) If true (>0) then correct the data for the shape of the antenna bandpasses using the BP table specified by BPVER. The correction has five modes: (a) if DOBAND=1 all entries for an antenna in the table are averaged together before correcting the data. (b) if DOBAND=2 the entry nearest in time (including solution weights) is used to correct the data. (c) if DOBAND=3 the table entries are interpolated in time (using solution weights) and the data are then corrected. (d) if DOBAND=4 the entry nearest in time (ignoring solution weights) is used to correct the data. (e) if DOBAND=5 the table entries are interpolated in time (ignoring solution weights) and the data are then corrected. BPVER......(multi-source) specifies the version of the BP table to be applied. 0 => highest numbered table. SMOOTH.....Specifies the type of spectral smoothing to be applied to a uv database . The default is not to apply any smoothing. The elements of SMOOTH are as follows: SMOOTH(1) = type of smoothing to apply: 0 => no smoothing To smooth before applying bandpass calibration 1 => Hanning, 2 => Gaussian, 3 => Boxcar, 4 => Sinc To smooth after applying bandpass calibration 5 => Hanning, 6 => Gaussian, 7 => Boxcar, 8 => Sinc SMOOTH(2) = the "diameter" of the function, i.e. width between first nulls of Hanning triangle and sinc function, FWHM of Gaussian, width of Boxcar. Defaults (if < 0.1) are 4, 2, 2 and 3 channels for SMOOTH(1) = 1 - 4 and 5 - 8, resp. SMOOTH(3) = the diameter over which the convolving function has value - in channels. Defaults: 1,3,1,4 times SMOOTH(2) used when input SMOOTH(3) < net SMOOTH(2). BPRINT.....Start listing at the BPRINT'th data point selected BEFORE applying the above criteria. (N.b. this is a change made 2 May 1997; previously BPRINT applied after application of the other sselection criteria.) NPRINT.....List NPRINT data points (after all data selection has been applied). 0 => 30000 on CRT or to a file, 1 page on printer. To printer the maximum printed is 2000 points, if printed to a file there is no limitation. Be aware that UVPRT now goes through the data to be printed twice, once to determine the u-v-w, data, and weight ranges and the second time to print things. Using NPRINT to reduce the time required by the first pass helps when DOCRT is true. XINC.......List every XINC'th data point from those matching the above criteria. 0 => 1. WTUV.......Scale the U, V, and W values in wavelengths by multiplying by WTUV. 0 => 0.001, i.e. Kilo wavelengths. DPARM......Range of (U,V,W), amplitude and weight: (1) : < 0 => Range of (U,V,W), amplitude and weight is determined automatically; If the data are large, the time for required additional pass of the data to provide the scaling can be rather large. To eliminate this extra pass use DPARM(1)=0. >= 0 => The ranges are fixed to the following values: (2) : Maximum weight; 0 => 9.9 (3) : Minimum weight; 0 => 0.11 (4) : Maximum amplitude; 0=>99 (5) : Maximum of ABS(U),ABS(V),ABS(W) in lambda times WTUV (normally klambda); 0 => 10000 (6) : > 0 => print phases from -90 to +269, otherwise from -180 to +180. The former gives a blank space between the amplitude and phase at all times. (7) : 0 => Print amp, phase 1 => Print real and imaginary (10) : Multiplier for amplitudes. DOCRT......False (<= 0) use the line printer if OUTPRINT = ' ' else write named OUTPRINT file only. When OUTPRINT is not blank, DOCRT=-2 suppresses the page-feed character on page headers and DOCRT=-3 suppresses page headers and most other header information. True (> 0) use the terminal interactively. The task will use the actual terminal width as a display limit unless 72 < DOCRT < width. In that case, the display limit will be DOCRT characters. OUTPRINT...Disk file name in which to save the line printer output. ' ' => use scratch and print immediately for interactive jobs - batch jobs use OUTPRINT = 'PRTFIL:BATCHjjj.nnn' (jjj= job #, nnn = user #). When OUTPRINT is not blank, multiple outputs are concatenated, and the file is not actually printed. BADDISK....Disk numbers to avoid for scratch files. Scratch files may be created by the sorting routines if calibration or flagging is applied. ----------------------------------------------------------------
