AIPS HELP file for CALRD in 31DEC18
As of Tue Apr 24 7:58:50 2018
CALRD: Task to read in a calibrator FITS image file
OBJECT Object name
BAND Code for arrays and band
OUTDISK 0.0 9.0 Disk drive # (0 => any)
Use: CALRD loads an image of a calibration source from the standard
AIPS area in which such FITS files are distributed.
OBJECT.....The source name, e.g. 3C138
BAND.......The band code, e.g. K perhaps with array code e.g. AK
although no array codes are used at present or frequency
OUTDISK....The disk drive #. 0 => highest with space
The input FITS file is INFILE='area:OBJECT_BAND.MODEL' where area is
either AIPSTARS or FITS in that order. The output image has
OUTNAME='OBJECT_BAND'; OUTCL='MODEL'; OUTSE=0 (usually ends up 1).
Blanks are squeezed out so that there are no blanks preceeding the
underscore in the names.
Use CALDIR to determine what models exist.
Note, to use these as calibrators, you must enter a total flux in the
source table which is correct for your observing frequency. Then
CALIB will scale the flux in these models to that total flux.
These models are in J2000 coordinates. If your data are in B1950,
either change the uv data to J2000 with UVFIX or change the images to
B1950 with EPOSWTCH.
For the JVLA we are going to produce models at more closely spaced
frequencies. One band so far has this done
Name BAND actual frequency
