python3-fitsio - 1.1.8+dfsg-1+b4 main

Fitsio provides an easy to use object-oriented API including
providing a Numpy interface to FITS files read from CFITSIO. It
allows direct access to the columns of a FITS binary table which can
be useful for reading large fits files. Compared to astropy.io.fits,
this package is closer to the underlying cfitsio library.
.
Fitsio also exposes a microlanguage (implemented in CFITSIO) for
making efficient SQL-like queries of tables (single tables only
though–no joins or anything like that).
