The ATCA Forum

Flagging data from CABB can be quite difficult as there are a large number of channels and the data volume is great. MIRIAD has undergone some improvements recently to assist users while flagging CABB data. The routine blflag has been improved, and a new option made available: nofqaver. Using this o...

Hi everyone! Welcome to the ATCA Forum forum. This post describes what I envisage for the ATCA Forum. I see this as a place to discuss anything that is preventing you getting the most from your ATCA data. If you've noticed some peculiarity in your data that you don't understand; if you're not reachi...

It was brought to our attention that the 7mm receiver was producing measurements of polarisation that were 90 degrees away from the expected values. It was determined that this could be caused if: the probes are mislabelled and one of them has reverse polarity the probes are rotated by 90 degrees Bo...

This forum is not meant as a replacement or even a duplication of the normal on-line fault reporting system at the ATCA. Instead, this is meant to be a place to discuss more subtle problems that may be affecting your data. For example, you should report that an antenna is faulty and needs to be stow...

During an attempt to determine the flux density of 1934-638 at frequencies above 30 GHz, Mark W. and I found that the Uranus brightness temperature varies in a way that is not accounted for by MIRIAD. MIRIAD has a brightness temperature for Uranus that varies by frequency, but does not account for a...
