James, The ID number for GOES10 is 74. The problem with copying the GOES-9 entry is that GOES-9 was 72, GOES-8 is 70 (The sounders onboard are instrument numbers 71, 73, 75). for example, GOES10 VIS 30 220 74 1 0 vis_upc.tbl GOES10 IR_3.9 0 255 74 2 0 GRAY GOES10 WV_6.7 0 255 74 4 0 wv_upc.tbl GOES10 IR_10.7 0 255 74 8 0 ir_upc.tbl GOES10 IR_12.0 0 255 74 128 0 GRAY The "raw" flag "1" would be used for uncalibrated images; however, all the IDD AREAfiles are calibrated, so the brightness values are 0 through 255.
