For an assignment, I've been told to divide up the galaxies with a Virgo Cluster Catalog number into early and late-type galaxies using the GOLDMine database, http://goldmine.mib.infn.it:8080/
Accessing the data required for analysis is not a problem,
(Search by Parameters -> (Tick VIRGO cluster) QueryGOLDMine -> (Tick Type) Get output)
but I do not understand what the numbers listed for the galaxy type mean.
I originally thought they represented a galaxy's Numerical Hubble stage, but then realized the data contains numbers outside of the Hubble stage. (E.g 20 for VCC0003.)
What morphological classification scheme is the database using?
