TLCAL: Converts a JVLA telcal file into an SN table
INNAME Input UV file name (name)
INCLASS Input UV file name (class)
INSEQ 0.0 9999.0 Input UV file name (seq. #)
INDISK Input UV file disk unit #
DOAPPLY -1.0 1.0 >0 Apply any SU table fluxes
**** Highly recommended ****
file name in (1) and (2)
else Last part of file name
with (2) = ' '
Use: Reads a JVLA telcal file and converts the complex gains and
delays into an SN table. This can then be applied to the CL
table with CLCAL. Note, if you run SETJY before running TLCAL,
then you can use the SU table fluxes to scale the amplitudes of
the known calibrators. Then, after TLCAL, you may run GETJY to
determine the fluxes of the secondary calibrators before running
CLCAL to apply the SN table to the data set CL table.
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.
DOAPPLY....If > 0, apply any fluxes found in the SU table to the
amplitudes found by telcal when writing the SN values.
HIGHLY RECOMMENDED: see above.
ASDMFILE...(1) Last part of file name without the .GN at the end
ASDMFILE(2) must be blank (' '). If it is not blank
the task will use the alternative below.
The telcal files are located at the path name:
!! ASDMFILE(1) !! .GN.
The task will supply the /home/mchammer and year and
month parts and the .GN. You need to provide the file
indentifier part such as C_quad1234_016.58274.92804802083
which is the same as the identifier part needed by
BDDFLIST and BDF2AIPS. Be sure to omit the close quote
so that case is preserved in the adverb value.
An alternative if you have obtained the .GN file from
mchammer already: Use both ASDMF(1) and ASDMF(2) to
specify the full path to the .GN file (but leave off the
.GN which the task will append). This could be the same
values for ASDMF as used by BDFLIST and BDF2AIPS if you
put the .GN file in the same directory as the top
directory of the SDM/BDF files.
