fxcor error “Aperture list cannot be applied to templat
cjsifon wrote on Mar 15, 2010
Hi, I'm trying to get redshifts for some gemini-south spectra with fxcor using the SDSS template spectra and I get the following error:
Warning: setting CD2_2 to 1.
Aperture list cannot be applied to template image.
The parameters of fxcor as the default ones (see bottom). What is causing this and how can I fix it?
Thanks a lot!

FXCOR currently only allows for 1-D templates, or 2-D templates where the aperture lists can be matched with the object. This specific error message happens when only one spectrum is found in the object, but the template appears to have more than one spectrum and the aperture list doesn't apply.
You can use the SLIST task to see how many spectra the code thinks are in the file, and perhaps then use SCOPY to copy out just the spectrum you're interested in. I'm not familiar with the SDSS spectral format, it could also be that the header has keywords that are confusing things. The warning about the missing CD2_2 keyword might imply a non-standard header, could you post a long listing?

Thanks for the reply. I'll have a look at what you mentioned.
I'm sorry, what do you mean by long listing?

The error message comes from the fact that the image is 2-d (4197x4) but there is a partial description of the WCS for a 1-D spectrum. Setting the CD2_2 value to one basically means there is no WCS along the second axis, but there are also no keywords to indicate what the 4 rows represent. If the spectrum itself is on row 1 then you can use an image section to make the file appear as a 1-D spec, e.g. "sp-023.fit[*,1]".
The object header you sent is is for the primary header of an MEF file, and it contains an equatorial WCS for a 2-D image and not a spectrum. Presumably the spectrum is in an extension, so you'll need to be sure to include the extension name when passing it to the FXCOR task. Even is this extension contains a multispec format spectrum, you should be able to correlate each aperture against the onedspec template given with the section, or else the aperture parameter would apply only to the object.
You might also look at the SCOPY task as a way to pull out the spectra and apertures into simpler image files. Hope this helps.
