The image is linearly scaled in an identical manner as the corresponding count rate map, such that the maximum pixel value (255) corresponds to a maximum value of 1.372 counts per minute. The actual error values are much smaller than the maximum value. Conversion from Digital Number (DN) to science value is given by the equation: SCIENCE_VALUE = (DN * 0.00538) GRS Potassium Gamma-Ray Count Rate Error Map kgcrerrmap 0 2 Last Index Fastest UnsignedByte counts/minute 0.00538 Line 360 1 Sample 720 2 0 1.372 0 grs_dap_k_gcr_err.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed grs_dap_k_gcr_err.jp2 2013-12-19T16:23:56.000Z 0 J2C Original JPEG-2000 image in PDS3 archive
