This menu loads a list of data file from Astrometry, Interferometry,
Spectroscopy, and Photometry. This menu is at the top of the so-called "Amoeba"
section, which handles multiple nights of data. The idea behind combining different
data, e.g. from astrometry and spectroscopy, is to be able to determine physical
parameters of binaries, like component masses, directly through fitting. The
photometry section is the least developed so far.
