Subject: mos-spectra error with SAS_MEMORY_MODEL set to low

Dear Helpdesk,

With SAS_MEMORY_MODEL set to low, a call to mos-spectra results in the error
attached at the end of this email (I Ctrl+C it after I get the error).
However, when SAS_MEMORY_MODEL is set to high, the problem disappears,
although it gives me the following warning:

** evselect: warning (DssFitsWrite), The data subspace specification has
become too complex(component 10, filter 10) to be able to write using the
FITS keyword conventions. The data subspace information stored in the FITS
files will be incomplete.

Nevertheless, this time, before getting the warning above, the task *
evselect* does select a certain number of rows from the input table (unlike
before).

I have full permissions (chmod 777) for all files I work with, including
those in the ccf/esas_caldb folder.

I would be very grateful for any suggestions on how to run mos-spectra
successfully.

Thank you,
Georgiana

PS: I run SAS 11.0.0, and work on a computer with Ubuntu 8.04.

Dear Georgiana,

The error you get does not seem to have anything to do with SAS_MEMORY_MODEL.
Leave it to high. We should look somewhere else. Could you send me the contents
of the reg.txt file ?

Dear Ignacio,

The reg.txt file does not exist. I am trying to extract spectra for the whole
field. Initially I ran mos-spectra without specifying regfile at all and thought
that adding it might make a difference, but it didn't.

Georgiana
