Task: This procedure runs TI2HA on each, single-source input UV data
set, INSEQ through IN2SEQ of the same INNAME and INCLASS, to
convert all times to hour angles (+ 1 day). It will sort the
output files to BT order with UVSRT and then concatenate the
altered/sorted files as it procedes using DBCON with
DOARRAY=-1. Finally, it will run UBAVG on the full
concatenated data set to average the data with
baseline-dependent time averaging. It ends with a UVSRT to
sort to TB order for imaging and self-calibration.
It is not required that all sequence numbers from INSEQ through
IN2SEQ actually occur. The loop will skip over missing ones.
You must first compile the procedure via
Then you may execute it by simply entering the word STUFFR.
The procedure will be remembered in the lASTEXIT SAVE/GET file
and so does not need to be re-RUN.
The input files must be single-source files having the same
antennas. The output should be used for self-calibration only
with care since times from multiple days will be mixed
together. Note that STUFFR now applies FG tables and SN
tables in the TI2HA step. Also note that flag, calibration,
weather, et al. tables must be discarded at that step since the
times in them no longer correlate with the "times' (actually
hour angles +1 day) in the data.
The procedure makes lots of intermediate UV files which it
deletes as soon as possible while it runs. This means that
certain names may not occur on your data disks. These are
name class seq numbers
------ ------ ---------------
INNAME HATMP INSEQ - IN2SEQ
INNAME SRTEMP INSEQ - IN2SEQ
INNAME DBCTMP INSEQ - IN2SEQ
OUTNAME UBATMP <GETPOPSN> (the aips number)
OUTNAME OUTCLASS OUTSEQ
The procedure will check for these names and quit if any of
them are present at the start of the procedure.
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.
IN2SEQ.....Highest sequence number for input UV files.
DOCALIB....If true (>0), calibrate the data using information in the
highest numbered (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). Calibration and flagging are applied to the
inputs to TI2HA.
FLAGVER....0 => flag each data set with its highest numbered flag
table; -1 => do no flagging.
OUTNAME....Output UV file name (name). Standard defaults.
OUTCLASS...Output UV file name (class). Standard defaults.
OUTSEQ.....Output UV file name (seq. #). 0 => highest unique
OUTDISK....Disk drive # of output UV file. 0 => highest with
space for the file.
APARM......UBAVG enrichment parameters.
(1) This gives the maximum averaging time in seconds,
0 => infinite. This parameter may be necessary if
subsequent editing may be required.
(2) This is the desired field of view (radius) which is
not to be distorted due to time averaging in minutes
of arc. 0 = > 20.
The field of view is the region in which averaging
is not to reduce the amplitude by more than 1 percent on
any baseline. No data separated by more than 268.5
wavelengths divided by APARM(2) are averaged
sinc(.0781) = 0.99 and .0781 * 60 *180 / pi = 268.5.
