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.

On MWAX_CORRELATOR observation 1320412440 (SUCCESS!)

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:

...

This outputs hyperdrive_solutions.bin.

RTS

...

Using these solutions in vcsbeam requires >= v2.18.16.

Fingers crossed this solution is still suitable for my observation!
