- pyirf.io.create_background_2d_hdu(background_2d, reco_energy_bins, fov_offset_bins, extname='BACKGROUND', **header_cards)[source]
Create a fits binary table HDU in GADF format for the background 2d table. See the specification at https://gamma-astro-data-formats.readthedocs.io/en/latest/irfs/full_enclosure/bkg/index.html#bkg-2d
- Parameters:
- background_2d: astropy.units.Quantity[(MeV s sr)^-1]
Background rate, must have shape (n_energy_bins, n_fov_offset_bins)
- reco_energy_bins: astropy.units.Quantity[energy]
Bin edges in reconstructed energy
- fov_offset_bins: astropy.units.Quantity[angle]
Bin edges in the field of view offset.
- extname: str
Name for BinTableHDU
- **header_cards
Additional metadata to add to the header, use this to set e.g. TELESCOP or INSTRUME.
