[Difx-users] complex support

[Phillips, Chris (CASS, Marsfield)]

Hi Jayce,

I am pretty sure double sideband is broken in the DIFx 2.6 release.

Can you please test the trunk version of DIFX. I started working on a new dot release of 2.6, but never got it completed. If you find trunk works OK then I will be motivated to finish making the new release. It is fairly small # changes (a few things got missed on the last dot release).

Cheers
Chris

Complex double sideband has now been much more extensively tested in DiFX trunk but mainly for one specific case, which is data from ASKAP (so that is CODIF format, and lower sideband.)  So it depends a little on your setup is.  If you provide some more details on the data source and the configuration, we might be able to provide some advice (or a short data file is always helpful if that is possible.)

Cheers,
Adam

Hi,

I was wondering what the status of complex double sideband support is in
DiFX?  I had found something that suggests that it should work but that
it was largely untested.  The reason I ask is that I have been
attempting to use it but I keep ending up with results don't make sense.
  I am trying to figure out if it is the data, my configuration, or
something within DiFX itself.

Thanks,
Jayce
