    1919This proposed correction will also replace the PATTERN.CELL correction.  This correction currently attempts to match the median background level of a cell that requires correction to the median across the OTA.  This often causes issues where bright stars in the cell to be corrected (or gradients across the field) create a bogus result that does not match that cell to the expected level.  By forcing cell edges to match, the new correction should obtain a better estimate of the correct level for the sagging cells.
