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.

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:

Set up initial RTS job

First, we need a calibration metafits file (mode = 'HW_LFILES'), which for the moment I edited by hand. It doesn't matter whether the file is one with PPDs or without, but apparently some script somewhere is expected the file to be called \[obsid\]_metafits_ppds.fits. So I manually edited the (MWAX VCS) metafits file and just changed the mode, and then made a symbolic link to is called /astro/mwavcs/vcs/1320499816/cal/1320499816/rts/1320499816_metafits_ppds.fits.

Set up initial RTS job

First, we need a calibration metafits file (mode = 'HW_LFILES'), which for the moment I edited by hand. It doesn't matter whether the file is one with PPDs or without, but apparently some script somewhere is expected the file to be called \[obsid\]_metafits_ppds.fits. So I manually edited the (MWAX VCS) metafits file and just changed the mode, and then made a symbolic link to is called /astro/mwavcs/vcs/

...

1320499816/cal/1320499816/

...

rts/

...

1320499816_

...

For an as yet unknown reason, this RTS job timed out, even after allowing 4 hours of wall time.

Beamforming

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

...

metafits_ppds.fits. Then I ran the script from VCSTools:

There's no good reason I couldn't have left off the --nosubmit option and had it run, but I just wanted to check it worked before trying it.
