hi All,I am using apextract for IFU spectra. We have 1300 fibers. I get the keywords:APNUM###there is only three digits. In my case it goes all the way to APNUM999actually if I look at apertures around 100 I see:APNUM100= '1009 1009 3098.03 3100.03'
APNUM101= '1019 1019 3130.32 3132.32'
APNUM102= '1029 1029 3162.37 3164.37'
APNUM103= '1039 1039 3194.18 3196.18'
APNUM104= '1049 1049 3223.37 3225.37'
...it obviously is writing the apertures above 1000, but there is no room in the FITS keyword, so it gets written, missing the fourth digit. For instance, apertures 1000 - 1009 get all written as APNUM100, surviving only the last one,1009Any suggestion for a quick solution to this?cheers,Antonio

hi folks,no luck yet. I changed APNUM to AP in smwm.x in apextract. Now the files get written with AP1 through AP1234 in the header.However, when I run identify it won't find the APNUM keyword and balks with:Warning: Image header parameter not found (APNUM1)makes sense, so I looked aroung for APNUM in onedspec and twodspec and found several ocurrences of this word in the noao/onedspec/smw directory. I replaced all ocurrences of APNUM for AP. Didn't help, I still get the same error message from identify. So, my new question is: where does identify get this from ? :-)thanks for your attention,Antonio

I'm sorry I did not respond sooner. It sounds like you are on the right track. I would have done the same thing with grepping and replacing. I can't say why it is not working. It is common to get confused about how to rebuild things so maybe you are not actually getting the changes you made. If you want to tell me which files you modified (or send them to me valdes@noao.edu) I can try and reproduce it.Frank Valdes
