(elo, ehi, specresp=None, exposure=None, ethresh=None, name='user-arf')[source] [edit on github]¶ Create an ARF.
New in version 4.10.1.
Parameters: - ehi (elo,) – The energy bins (low and high, in keV) for the ARF. It is assumed that ehi_i > elo_i, elo_j > 0, the energy bins are either ascending - so elo_i+1 > elo_i - or descending (elo_i+1 < elo_i), and that there are no overlaps.
- specresp (None or array, optional) – The spectral response (in cm^2) for the ARF. It is assumed to be >= 0. If not given a flat response of 1.0 is used.
- exposure (number or None, optional) – If not None, the exposure of the ARF in seconds.
- ethresh (number or None, optional) – Passed through to the DataARF call. It controls whether zero-energy bins are replaced.
- name (str, optional) – The name of the ARF data set
Returns: arf
Return type: sherpa.astro.data.DataARF instance
