Identifying lines in IRAF

epud wrote on Mar 10, 2011

This is all good and well, but how do I create a reference spectrum which I can use to identify the lines? I would like to give my students a page containing a spectrum with the lines identified. The arc lamp I need is Rubidium. So basically I want pre identified spectrum printed out on a sheet of paper. Can I make this in IRAF? Where can I find this?

Thanks

The result I am looking for looks like this:

Now this is for a ThAr lamp. I need one for Rb. I don't need it to be grism specific or anything.

I fyou have a list of Rb lines you can use the MK1DSPEC task in the ARTDATA package to create an artificial spectrum (see the help page examples), likewise you could format this list to be used with the IDENTIFY task to create the plot you want. However, IRAF doesn't include any Rubidium information otherwise so you'll need to get this linelist elsewhere.
