                                           FITSProdGrammar

A grammar that returns FITS-headers as dictionaries.

This is the grammar you want when one FITS file corresponds to one row in the destination table.

The keywords of the grammar record are the cards in the primary header (or some other hdu using the same-named attribute). "-" in keywords is replaced with an underscore for easier @-referencing. You can use a mapKeys element to effect further name cosmetics.

This grammar should handle compressed FITS images transparently if set qnd="False". This means that you will essentially get the headers from the second extension for those even if you left hdu="0".

The original header is preserved as the value of the header\_ key. This is mainly intended for use WCS use, as in ``wcs.WCS(@header_)``.

If you have more complex structures in your FITS files, you can get access to the pyfits HDU using the hdusField attribute. With ``hdusField="_H"``, you could say things like ``@_H[1].data[10][0]`` to get the first data item in the tenth row in the second HDU.
