[McIDAS #AKP-990660]: GOES-12

Hi Waldenio,

re:

> 4 and 5. There is no 13.3 Microns channel ?

No, GOES-12 does provide 13.3 um coverage.  Here is a BAND listing from
McIDAS for GOES-12 images being ingested here in UCAR:

As you can see from this list, BAND 6 is 13.3 um.

Is this listing from GEMPAK, and, if yes, what version of GEMPAK are you 
running?

re:

Please let me know if the BAND listing from McIDAS for GOES-12 images helps you.

Also, in regards to the note that Ana sent:

It is very likely that the McIDAS tables being used by your old (2004)
distribution of ldm-mcidas do not have the needed up to date information.
There is a new version of ldm-mcidas (2008) that you can download and use.

Please let me know if my comment above was not the solution for the
problems that Ana reported.
