19990105: Problem setting Nsat enhancement default
- Subject: 19990105: Problem setting Nsat enhancement default
- Date: Tue, 05 Jan 1999 13:31:20 -0700
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.
