The problem is when I run the task COMB,
Opcode: 'POLC' to calculate the polarized intensities. It is suppose to
compute a noise correction which corrects for the bias introduced when
combining the Stokes Q and U images. It does not seem to take this noise
correction into account so I get only positive noise values, when I am
suppose to get both positive and negative noise values. I have done this
many times in AIPS and it has worked perfectly before. I had this same
problem last year when running ''AIPS'', but I switched to ''AIPS NEW''
and it was working fine. For some strange reason it has stopped working
in ''AIPS NEW'' but I only noticed about a week ago. I asked a colleague
to try running the same task in his computer and it also doesn't work
properly on his.
