lsst.ip.isr.electrostaticBrighterFatter.electrostaticBrighterFatterCorrection	(		log,
			exposure,
			electroBfDistortionMatrix,
			applyGain,
			gains = None,
			applyFilterCorrection = False )

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.
