Methods Documentation

correct_photometry(radius=None, ytransfers=None, mjd=None, local_skys=None, fluxes=None)

Get the CTE corrected FLT photometry.

Parameters
  • radius ({3, 5}) – Aperture radius used to extract photometry.

  • ytransfers (float, list) – Number of row transfers. For chip 2 on WFC, this is the Y value. For chip 1, it is 2048 - Y.

  • mjd (float) – MJD date of the observation.

  • local_sky (float, list) – Local sky background for each source in units of electrons.

  • fluxes (float, list) – Computed source flux, in electrons, for 3 or 5 pixel apertures.

Returns

corrected_magnitudes – If the query is successful it returns the CTE corrected magnitudes for the sources. Otherwise, it returns None.

Return type

numpy.array, None
