I want to write >temperatures and I cannot find the correct image source type. After perusing the online McIDAS Programmer's Reference Manual: http://www.ssec.wisc.edu/mug/prog_man/prog_man.html I thought I found a way for you to do this using the PRD calibration type, but it turns out that this is only for 1-byte data. I learned this by calling Dave Santek of SSEC and talking about what you are trying to do for about a half hour. Dave had two comments: 1) your reverse engineering to get counts that represent temperatures was the best approach in your HDF to AREA conversion 2) he is going to send you some code they have that will convert raw GMS image scans into McIDAS AREAs (this relates to the conversation we had in my office yesterday, not to this email). So, the answer to your simple question is _no_, there is not another way of writing temperature values directly into an AREA file. >Thanks >Darren Tom
