Hi Hsie,

I hadn't noticed that these have not been sent since about March 6.  I
will look into this.

I just compared the sizes created on rainbow with sizes created by the
old filing scheme on a Linux machine here at Unidata, and the sizes
created on blizzard and the sizes created on motherlode.ucar.edu.  In
both cases, the sizes match between your and our systems (Linux to
Linux; Solaris to Solaris), but they are different between the two!

The only thing I can imagin is that the blank portion of the GOES-12
images is being included in the Solaris files but not in the Linux
ones.

I do a display of the image decoded on Solaris in one McIDAS frame and
the same image, loaded the same way from a Linux system, the displays
are identical.  Also, the data portion of the images are identical --
I just did a 'cmp' between the same image decoded by two different
methods, and they were identical up to the comment cards at the end of
the image.  It looks like the images decoded the 'old' way have extra
stuff at the end that is essentially blank and has no effect on
the information content of the image.

I will add looking into this into the set of ldm-mcidas development tasks.

Thanks for the keen eye!

Cheers,

Tom
