Hi Mark, Thanks, that’s very helpful to know. I’ve discussed this problem with other members of the ATLAS team and given that this is a fundamental problem due to the low number of antennas we’ve decided not to apply amplitude selfcal. We are extracting source counts from the data so it’s important ...

I have encountered a problem with amplitude self-calibration. I have been applying this to individual pointings at 1.3-1.8 GHz. I am finding that amplitude selfcal is affecting the fluxes of faint (SNR < 50 or S < 1 mJy) sources – see plot below which compares the flux after amplitude selfcal with t...

Hi, I have been thinking about how best to image some wide-band CABB data. I am using 800-MHz of data, from 1350 to 2150 MHz. I have many pointings which I need to combine to form a mosaic. To improve the accuracy of the primary beam correction, I have decided to split the band into 4 sub-bands so t...
