Hi Charlie,
I think that creating miriad files that are closer to those that are produced by miriad itself would be a generally good
thing, so if you are willing to spend some time on this I would appreciate it. I would be happy to show you the same miriad
data created through the native and MIR channels to make clear the header differences if that would help.

      Hi Dan,
Thushara told me that after the use of "old readdata", some basic bandpass cal with polar keyword didn't work. So I am
going to check what went wrong.  If you would like to fill in new miriad header, I can try or I can seek help from
Sheng-Yuan.

      Great, thanks Charlie. You'll look at the use of "old readdata" or the idl2miriad function?
on the readdata side, it ultimately did complete and it used uti_uvw_fix on 4-7 for some reason that I could not
discern

      Hi Dan,

This is the second time I got report about this problem for polarization track. Interestingly it was
yesterday I got the first report from Thushara about similar problem for a 2009 polarization track. I am
attending an IAU meeting at Canada now. I will take a look when I am back this weekend.
