Hi Frank,

we have being testing the new version of "soimosaic", modified by you 
and, after a quick fix (0 instead of "0") in the imcombine its working 
fine, including fractional pixel shifts.

Thanks a lot for your help.

My best wishes,

Eduardo

Hola Eduardo,

Thanks for the data.  I did not try to understand the error message  
which has to do with the way some world coordinate keywords are being  
handled.  I think MOVEHEADER was written for a specific situation  
with HST data.   I also see IMTILE is limited in that it does not  
move do anything reasonable with the header information.  As I  
mentioned, I recommend using IMCOMBINE with the offsets="grid"  
option.  I have taken the liberty of modifying your script
so it works as you want.

Regards,
Frank

Dear Frank Valdez,

no problems at all !

Unfrotunatelly, since most users will want to bin the CCD's fractional
pixel shifting in needed.

In

ftp://ftp.ctio.noao.edu/cypriano/Frank

you may find two images: mosaiced and non-mosaiced, as well as a  
copy of
the script used for the mosaicing.

You may find the headers of those images (5 for the non-mosaiced  
one and 1
for the mosaiced) attached to this e-mail.

Bye,

Eduardo
