"auto" selection falling over

[o-smirnov]

So this MS is dead simple:

However, running it with auto for the various calibrators in observation_config results in:

Selecting the fields manually seems to work. So I guess auto is broken in master. Or broken for me, anyway.

I think recent changes by @SpheMakh mean that 'auto' selection is no longer valid. For calibrators, you could go with 'all' or 'longest' or 'nearest' or the field name and for target you could go with the name or 'all'. Like in the MeerKAT defaults:

observation_config: 
  obsinfo: 
    enable: true
  target:
    - 'all'
  gcal: 
    - 'all'
  bpcal:
    - 'longest'
  fcal:
    - 'longest'
  xcal:
    - 'longest'
  reference_antenna: '0'
  plot_elevation_tracks: true

Ah. :)

Well being the professor, I'm allowed to miss the redefinition of options...

Thanks @KshitijT, it was exactly that.
