The values in this table are used to calculate the amount of cross-talk to be removed from an IR spectral image. When an IR image is displayed using the FITS standard, fastest varying index to the right and slower varying index up, then the left half of the image is quadrant A and the right half is quadrant B. At this time, the cross-talk is negligible across the IR quadrants, so all values in this table are set to zero. This prevents the calibration pipeline from performing a correction for the crosstalk signal."
