Remove Healpix requirement for easy cluster management

[nicholebarry]

When refreshing the info file, the Healpix cubes are required, even if the uvf_cubes exist. It would be best to extract the information from the Healpix cubes into the uvf_cubes so that the Healpix cubes don't need to be downloaded for aws users.

Example: Mike downloaded the uvf cubes from aws to a local computer. He then tried to refresh_info.

IDL> ps_wrapper, "/Volumes/Faramir/2014_GS/2014_PS/GS_freq_broadcast_dgpb", "Combined_obs_2014_GS_plus_one", /refresh_info, /refresh_beam, /png
% PS_FILENAMES: No cube or info files found in folder /Volumes/Faramir/2014_GS/2014_PS/GS_freq_broadcast_dgpb

So all the required information from the HEALPix files is extracted and saved in the info file. So the solution is to not have to refresh info. Why was that needed?

[nicholebarry]

I copied the uvf cubes and the info file from the cluster onto my local computer, and tried to run eppsilon to see if the refresh_info keyword was needed or not.

So I just ran into this and I think I understand the confusion better now. The issue (at least in my case) is that in addition to the uvf_cubes, eppsilon also needs the beam_cubes, which are stored in the ps folder under data/beam_cubes. If those are present, the info file should not need to be refreshed and the Healpix cubes should not be needed.
