Attributes Documentation

corrected_magnitudes

CTE corrected magnitudes

cte_corrections

Computed CTE corrections

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.

ytransfersfloat, list

Number of row transfers. For chip 2 on WFC, this is the Y value. For chip 1, it is 2048 - Y.

mjdfloat

MJD date of the observation.

local_skyfloat, list

Local sky background for each source in units of electrons.

fluxesfloat, list

Computed source flux, in electrons, for 3 or 5 pixel apertures.

Returns:

corrected_magnitudesnumpy.array, None

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