create_aeff2d_hdu

pyirf.io.create_aeff2d_hdu(effective_area, true_energy_bins, fov_offset_bins, extname='EFFECTIVE AREA', point_like=True, **header_cards)

Create a fits binary table HDU in GADF format for effective area. See the specification at https://gamma-astro-data-formats.readthedocs.io/en/latest/irfs/full_enclosure/aeff/index.html

Parameters:

effective_area: astropy.units.Quantity[area]

Effective area array, must have shape (n_energy_bins, n_fov_offset_bins)

true_energy_bins: astropy.units.Quantity[energy]

Bin edges in true energy

fov_offset_bins: astropy.units.Quantity[angle]

Bin edges in the field of view offset. For Point-Like IRFs, only giving a single bin is appropriate.

point_like: bool

If the provided effective area was calculated after applying a direction cut, pass True, else False for a full-enclosure effective area.

extname: str

Name for BinTableHDU

**header_cards

Additional metadata to add to the header, use this to set e.g. TELESCOP or INSTRUME.
