electrostaticBrighterFatterCorrection

lsst.ip.isr.electrostaticBrighterFatterCorrection(exposure, electroBfDistortionMatrix, applyGain, gains=None)

Evaluates the correction of CCD images affected by the brighter-fatter effect, as described in https://arxiv.org/abs/2301.03274. Requires as input the result of an electrostatic fit to flat covariance data (or any other determination of pixel boundary shifts under the influence of a single electron).

The filename refers to an input tuple that contains the boundary shifts for one electron. This file is produced by an electrostatic fit to data extracted from flat-field statistics, implemented in https://gitlab.in2p3.fr/astier/bfptc/tools/fit_cov.py.
