Hello!I have a problem with the command "badpiximage" from the noao.imred.ccdred
package:if i try to use a 255^2 or a256^2 image as template
the first or first two lines from the top
get also the value "badvalue = 0".if i use the same image but image[1:254,1:254] or image[1:257,1:257]
nothing unusual happens.can you reproduce this?
do you know this effect?
is there a possibility to avoid this ?

Subject: Re: problems with "badpiximage"-commandHi Michael,I'd be glad to check this out. However, I would need the fixfile
information you are using. Please mail this to me. Also in
case it is host or version dependent let me know the type of
computer/OS and the version of IRAF (from the first line of the
login banner).Yours,

Subject: Re: problems with "badpiximage"-commandHi Michael,The bad news is that I have not been able to reproduce the problem.
The following shows what I did.NOAO DEC-ALPHA/IRAF Revision 2.10.4-p2 Wed Jun 5 17:12:08 MST 1996
This is the EXPORT version of DEC Alpha OSF/IRAF V2.10.4 for OSF/1 2.0. cc> type fix.dat
10 20 10 20
cc> badpix fix.dat dev$pix[1:256,1:256] test256
cc> minmax test256
test256 [10,10] 0. [1,1] 1.
cc> imstat test256[*,1]
# IMAGE NPIX MEAN STDDEV MIN MAX
test256[*,1] 256 1. 0. 1. 1.
So I need more precise example. Note the version is the patched version.
I don't have access to the earlier version. I am not aware of any
fix that might affect this.Cheers,
Frank[No further response as of 11/14]
