Positional error in restored image
Reducing year 2000 data- dual C/X data from C711. The reduction is nothing out of the ordinary, the usual invert, clean and restor tasks are run but when I load a kvis annotation file with known sources onto the restored image, the image is inaccurate by ~ 15 arcsec. Is there something I've forgotten?

Re: 1995 data reduction
Ok, thanks for that Mark. That will teach me to keep my notes and look at the data first!

Re: 1995 data reduction
Hi Jamie,
With gpcal, I only set vis and interval to 0.1 and 10 (the latter to see what would happen). I've placed the file (minus +/- 200 chans removed with uvflag) of 1934-639 in /data/KAPUTAR_1/mad134/
Cheers,
Stacy.

1995 data reduction
Yes, you read right, HI data from 1995. Using standard atlod, uvsplit, pgflag, blflag is okay, but when I get to gpcal: gpcal: Revision 1.14, 2012/10/15 01:32:52 UTC Applying bandpass corrections to ./1934-638.1420/ Number of antennae: 6 Reading the data ... ### Fatal Error: No data read from input ...
