The assumptions made in this procedure may not be the best - but it is a great help for lazy people. To run this procedure you MUST type > RUN VLARUN (I recommend typing 'RESTORE 0' first) to define the procedure (only once) in AIPS, and then > VLARUN to actually execute it (after reviewing the inputs!) Do FILLM and visibility FLAGGING before VLARUN (and also split the data into single-frequency files). This is the input dialog to the quick VLA pipeline There are NO DEFAULTS! It assumes you have observed 3C286 or another VLA amplitude calibrator (see HELP) for absolute amplitude calibration. It will use up to 2 sources (may be 3C286 etc) for bandpass in LINE, and can use up to 8 possible phase calibrator names. Bandpass calibrators defined by CALSOUR can be any (but maximum 2) sources in your data. It is only used for line data sets. When you run VLARUN with DOCONT < 1 the procedure will STOP once (very soon after starting) in the beginning, after GETJY so you can check your calibrator fluxes. When you run VLARUN with DOALL > 0 the procedure will do the imaging for you using IMSIZE, NITER and FLUX The procedure also makes plot files at critical stages of the calibration. View plots on the original multi- source files (also LINE) with: getn [catno]; allplot ----------------------------- BADDISK Disks to avoid for scratch INDISK Working disk, thus in/outdisk NCOUNT Catalog number of the UV-file must be 'ch 0' for line data SOLINT Solution interval for CALIB REFANT Good reference antenna number DOARRAY Max baseline in kilometers: A=35.4, B=10.8, C=3.3, D=1 Pixelsize=17.5/(GHz*doarray) UVRANGE Range for primary calibrator pre-defined; either one of: 3C48,3C138,3C147,3C286,3C295 or its IAU name, see HELP Edit the procedure for other CALSOUR Bandpass calibrators (max 2) CALSOUR only used for LINE SOURCES Phase calibrators (max 8, or '*' = any calcode CONTINUUM) All others are your targets! DOCONT Continue after GETJY, no stop DOALL Also do a split and imaging? -- ONLY USED IF DOALL > 0 -- IMSIZE Square size of image (pixels) NITER Max number of iterations/chan CUTOFF Min flux to consider in clean ---------------------------------------------------------------- VLARUN Type: Procedure Use: VLARUN is the procedure that applies VLA calibration $---------------------------------------------------------------------------- Type RUN VLARUN to define the VLARUN procedure CLEAN STARTING CONDITIONS Make sure only one frequency-ID is present (otherwise use UVCOP to split them apart and INDXR to index the files). Can process both continuum and line data, but the line files must have inclass 'CH 0' and 'LINE'. The flags must be made in the highest numbered FG table on the continuum or 'CH 0' files, so if you flag the 'LINE' data you have to copy the line flags/flag-table to the 'CH 0' file LIST OF ALL NAMES RECOGNIZED AS A VLA AMPLITUDE CALIBRATOR IN SETJY 3C48 is also known as: 0134+329, 0137+331, or J0137+3309 3C138 is also known as: 0518+165, 0521+166, or J0521+1638 3C147 is also known as: 0538+498, 0542+498, or J0542+4951 3C286 is also known as: 1328+307, 1331+305, or J1331+3030 3C295 is also known as: 1409+524, 1411+522, or J1411+5212 At least one of these names (3C or other) must be in the data set for the amplitude calibration. If a different source is used, then you have to edit the procedure twice (guidelines provided in the procedure). $--------------------------------------------------------------------------- VLARUN : Procedure to calibrate VLA data blindly.
