create_psf_table_hdu
- pyirf.io.create_psf_table_hdu(psf, true_energy_bins, source_offset_bins, fov_offset_bins, extname='PSF', **header_cards)[source]
Create a fits binary table HDU in GADF format for the PSF table. See the specification at https://gamma-astro-data-formats.readthedocs.io/en/latest/irfs/full_enclosure/psf/psf_table/index.html
- Parameters:
- psf: astropy.units.Quantity[(solid angle)^-1]
Point spread function array, must have shape (n_energy_bins, n_fov_offset_bins, n_source_offset_bins)
- true_energy_bins: astropy.units.Quantity[energy]
Bin edges in true energy
- source_offset_bins: astropy.units.Quantity[angle]
Bin edges in the source offset.
- 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.
- extname: str
Name for BinTableHDU
- **header_cards
Additional metadata to add to the header, use this to set e.g. TELESCOP or INSTRUME.
