The keywords defined in the #K records are available via the output table meta attribute:
>>> import os
>>> from astropy.io import ascii
>>> filename = os.path.join(ascii.__path__[0], 'tests/t/daophot.dat')
>>> data = ascii.read(filename)
>>> for name, keyword in data.meta['keywords'].items():
... print name, keyword['value'], keyword['units'], keyword['format']
...
MERGERAD INDEF scaleunit %-23.7g
IRAF NOAO/IRAFV2.10EXPORT version %-23s
USER name %-23s
...
The unit and formats are available in the output table columns:
>>> for colname in data.colnames:
... col = data[colname]
... print colname, col.unit, col.format
...
ID None %-9d
XCENTER pixels %-10.3f
YCENTER pixels %-10.3f
...
Any column values of INDEF are interpreted as a missing value and will be masked out in the resultant table.
