[AstroPy] synthetic photometry

[Thomas Vaughan]

I'm looking for a convenient package that I can use to do synthetic photometry.

I thought that I'd probably write one myself, but I should at least
see what's available.

Browsing the Web, I came upon astrolib.

Can it already be used for synthetic photometry?

I need to make a star catalog by starting from a subset of Tycho-2
photometry and spectroscopic classifications. I have the overall
response for my instrument. I need to define a magnitude system for
the instrument and to predict the instrument magnitude for each star
in the catalog.
