Imaging Channel Averaged UV Data
Posted: Fri Jan 29, 2021 11:36 am
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
