imreplace

[Guest]

Dear IRAF support group,

We write you because we are experiencing some
troubles using IMREPLACE.

We have IRAF 2.12.2a currently installed, and apparently Jan97 version of
the IMUTIL package.

We are using IMREPLACE for masking, by directly modifying .fits
object-masks, created with the OBJMASK task in the NPROTO (January 1992)
package.

When run, IMREPLACE seems to work correctly (no error message is
prompted), but afterwards, when using the resulting masks, we have a
"segmentation violation" message. Dysplaying the mask,
it turns out that it is "broken", i.e. no pixels are shown.
Even statistics fail (IMSTAT).

On a previous installation (2.12.1 IRAF version)
it all worked properly.

Is this a known bug? Is there a solution?
We looked on IRAF web page, but we only found a couple of reports
about imreplacing on .pl images and about the usage of the "radius"
parameter.
Note that we are using radius=0 and we are working on .fits frames,
hence these cases do not apply.

Thank you very much indeed,
best regards,

Stefano Berta
