hyperdrive di-calibrate -s srclist_1000.yaml -d /astro/mwavcs/asvo/252007/*.fits ${METAFITS}

This outputs hyperdrive_solutions.bin. The --tile-flags 57 corresponds to TileName HexE2. It is used because doing it without shows the amplitudes for that tile are much higher than the others.

Using these solutions in vcsbeam requires >= v2.19.13.

Weirdly, even though I flagged HexE2 in Hyperdrive (corresponding to Antenna #57), it still shows up in these solution plots. This might be a bug in Hyperdrive. Fornow, I'll just also flag it when I try to beamform.

Beamforming

All 24 channels

Beamforming directly from MWAX (which does the fine PFB on GPU memory) requires >= 3.2.1.

Unfortunately, this doesn't work on the gpubox files as written out by the legacy offline_correlator, which doesn't write out most of the metadata info that mwalib needs to correctly parse those files. I'll work on this route later.

At the moment, Harry is still helping me obtain the files. As it turned out, this obs was already downloaded for Cath and the EoR team, so Harry was able to just copy them to a place I can see them on Garrawarla: /astro/mwavcs/asvo/252007. Then, running them through Hyperdrive is straightfoward:
