Something wrong with "pgflag"
Posted: Fri Jan 13, 2017 3:53 am
Hi,
I am trying to reduce the raw data of one of our sources at 9GHZ (See https://atcaforum.atnf.csiro.au/viewtop ... f=21&t=270). Following instructions from the ATCA data analysis webpage, I used "pgflag" to do the flagging on this source. However, it seems to take forever in this step (at least ~5 hrs before I gave up) in any of the pgflag of stokes V, Q or U (such as: $ pgflag stokes=i,q,u,v flagpar=8,5,5,3,6,3 "command=<b"), and miriad seemed to pause with the following:
pgflag: Revision 1.29, 2014/10/24 04:16:34 UTC
Applying bandpass corrections to g345.81.9000/
Applying freq. dependent gain corrections to g345.81.9000/
Applying freq. dependent leakage correction to g345.81.9000/
I think something might be wrong with the calibrators or data, but I don't know where to start investigating this problem....
Thanks!
