Importing ATCA obs into CASA (ms file)
Hi all, I'm having some major issues converting an ATCA obs into a CASA measurement set. Currently I've tried to export the data with fits and then re-import it in CASA with importuvfits. I then tried to just import the ATCA obs folder with importmiriad. importatca just produces corrupt data errors....

Imaging Channel Averaged UV Data
Hi,
I've imported an ATCA uvfits file to CASA and made images for both a non-channel averaged and channel averaged data set. The channel averaged data appears to have a lower SNR, is this a common issue when averaging a poorly uv sampled observation?
Cheers,
Brodie

Re: Visibilities with FITS
For anyone else with this issue, I figured out a short time ago that the visibilities can be extracted from the uv data set using uvdump.

simobserve for ATCA
Hi all, I'm attempting to pass a radiative transfer model synthetic image through simobserve in CASA in order to measure the residuals between my 34GHz transition disk image (obs on 04/05/16) and a "degraded" synthetic image. I feel confident with most of the options in the task except for...

hd97048 radial extension
Hi, I'm getting some significant radial emission on the reduction of hd97048 (cucha) from the 30 aug 2014 track contrary to what was published in van der Plas 2017. Here's my reduction steps: 1. No seemon values flagged 2. BPcal 1253-055 - blflag on spread between 18h06m – 18h20m 33/35 GHz - flagged...

Re: mirpy
Hi Jamie, I was using the decode line because Malte suggest it. Currently I'm trying to run the python wrapper in an attempt to write an automated reduction pipeline - hence trying to output in a similar method as I would in the miriad bash. I've implemented your new atload_filter but I still get th...

Re: mirpy
ah yes - an embarrassing mistake. If I run this code below: from mirpy import miriad ddir='/Users/brodienorfolk/obs/c1794/*.C1794' def atload_filter(output): return output.decode() miriad.set_filter('atlod', atload_filter) miriad.atlod(In=ddir,out='uvdata',options='birdie,rfiflag,xycorr,opcorr,noaut...
