craverage and FITS plio masks

Maureen Conroy wrote on Apr 03, 2008

Hi Folks,
We've been making good use of the FITS storage for pl masks.
But we've stumbled with the "craverage" task. (This is still under
IRAF 2.12 for redhat).
We've add the "fpl" extension to the fxf in the imextn symbol.
As I understand, we must use the "[type=mask]" qualifier in the
file name to create the output crmask - BUT - the task then fails
when it needs to re-open and grow the data. (When specifying this
file for reading I've always supplied the "[1]" extension specifier.
(There is always just the single extension in our applications.)
So is there a better way to specify this that will work -
or is this a limitation - and I should just stick with vanilla
pl files for this application.

Thanks,
Maureen
