[AstroPy] How to append to a astropy.io.votable
Tue Apr 16 16:43:10 CDT 2013
i've been using atpy for VOTable manipulation and I'm working to switch to astropy.io.votable.
I don't see how 'add_column' to a table object?
>>> from astropy.io.votable import parse
>>> from astropy.io.votable.tree import Field
>>> t = parse('filename.vot').get_first_table()
>>> print t.array['newColumn']
ERROR: ValueError: field named newColumn not found. [numpy.ma.core]
I'd like to add a column to t where that column contains a computed value based on one of t's other columns.
