To read this table, do the following: Find the column corresponding to the "target" chip (the chip you want to read). Look for significant amplitudes. For each "cross-talk" chip that has a significant amplitude in the column, subtract the amplitude times the cross-talk-chip image from the target-chip image. (In principle, you need to do some column and row flipping, but in practice you don't because the non-zero amplitudes are for chip pairs with identical orientations.)
These coefficients were found with mosaic_crosstalk and mosaic_crosstalk_analyze in the astrometry.net codebase.
Briefly, the method is as follows:
The IDL code that performs these functions is
