[AstroPy] Python interface for querying Vizier?
Mon Jun 21 21:03:12 CDT 2010
I've been doing cone searches in Vizier using VO Desktop which has a
python module interface.
I don't think it has all of Vizier's functionality but you can
definitely search a catalog. There were some difficulties dealing with
the votable strings it returns but with a little StringIO magic and
one of several table readers out there (i use atpy
http://atpy.sourceforge.net/) you can get your data into a usable

Some equivalent to IDL's queryvizier.pro would be great, though of course a more Pythonesque object interface would be even better. Has anyone taken a stab at creating something like this? Or is there something in the VO toolkit that can do this sort of thing but that I don't know about? (I confess it seems hard for a relative outsider to the VO community to keep track of what's actually been built there so far...)
