Leonia,

As I said earlier I ran GETJY and things went well. The flux densities
of the calibrators were close to what is given in the VLA Calibration
Manual and the errors are of the order of 1 or 2 per cent. 

Progress is slow because I seem to find inconsistencies between Chapter
4 and Appendix B - at least for someone that have almost no experience
with AIPS I see it as inconsistencies. For one, in Appendix B.1.3 ,page
B-4, the procedure for calibrating line data is given. It starts with
SETJY, then VLACALIB, then GETJY and ***then again GETJY****. What made
me supicious is that the paramaters specified at the second call of
GETJY does not even appear when you list the input parameters for
GETJY. In Chapter 4 one the other hand, GETJY is executed only once and
after that, CLCAL. It was only after displaying the input parameters
for CLCAL that I decided the second call of GETJY in Appendix B.1.3 is
a typing error - or is it not?!! 

Now also compare the inputs of the CLCAL in chapter 4 (p 4-29) with
that on p B-4. I refer to the SOURCES and CALSOUR entries. For an
experienced user of AIPS it may not be a problem but for a novice like
me (for whom the CookBook is the only reference) it is rather
confusing. 

The same applies to the LISTR task that has to be run after CLCAL.
WHich table should be listed: SN or CL? Also, on p 4-30 it seems that
the sources should be listed by name explicitly while on p B-5 it is
not required to list the names. 

Johan
