We seem to employ both side of the argument here. The call for a spectroscopy section was turned down on the ground it was a technique and as it was mainly stars that were studied VSS was the right home. Now it seems that as Exoplants are mainly studied via photometery VSS should be its home.
I think the judgement should be on demand and potential contribution. Just how much overhead does a new section bring in the age of the internet?
