pint.event_toas.load_fits_TOAs

pint.event_toas.load_fits_TOAs(eventname, mission, weights=None, extension=None, timesys=None, timeref=None, minmjd=-inf, maxmjd=inf, errors={'IXPE': <Quantity 20. us>, 'NICER': <Quantity 0.1 us>, 'NuSTAR': <Quantity 65. us>, 'RXTE': <Quantity 2.5 us>, 'Swift': <Quantity 300. us>, 'XMM': <Quantity 48. us>, 'default': <Quantity 1. us>})[source]

Read photon event times out of a FITS file as a list of PINT TOA objects.

Correctly handles raw event files, or ones processed with axBary to have barycentered TOAs. Different conditions may apply to different missions.

The minmjd/maxmjd parameters can be used to avoid instantiation of TOAs we don’t want, which can otherwise be very slow.

Parameters:

  • eventname (str) – File name of the FITS event list

  • mission (str) – Name of the mission (e.g. RXTE, XMM)

  • weights (array or None) – The array has to be of the same size as the event list. Overwrites possible weight lists from mission-specific FITS files

  • extension (str) – FITS extension to read

  • timesys (str, default None) – Force this time system

  • timeref (str, default None) – Forse this time reference

  • minmjd (float, default "-infinity") – minimum MJD timestamp to return

  • maxmjd (float, default "infinity") – maximum MJD timestamp to return

  • errors (astropy.units.Quantity or float, optional) – The uncertainty on the TOA; if it’s a float it is assumed to be in microseconds

Returns:

toalist

Return type:

list of TOA objects

Note

This list should be converted into a TOAs object with pint.toa.get_TOAs_list() for most operations
