CrosstalkExtractTask
####################

``CrosstalkExtractTask`` measures the flux ratios between bright sources on one amplifier and the same location on the other amplifiers to look for crosstalk sources.

.. _lsst.cp.pipe.CrosstalkExtractTask-processing-summary:

Processing summary
==================

``CrosstalkExtractTask`` runs these operations:

#. Identifies bright sources on each amplifier.
#. Iterates over the other amplifiers, extracting those potential targets to ensure they have the readout corner placed at the same amplifier coordinate.
#. Measures the ratio between the background subtracted target location and the source amplifier location.

extract
    Display the exposure under consideration, with the pixels used for crosstalk measurement indicated by the DETECTED mask plane (`bool`)?

pixels
    Display a plot of the ratio calculated for each pixel used in this exposure, split by amplifier pairs.  The median value is listed for reference (`bool`)?
