I have used pyspeckit. There are parts of it that are very useful, but I found overall that it didn't do what I wanted. For example, I wanted to give it my spectrum, have it display it, allow me to manually (in the gui) place my guesses for line centers (would probably need guesses for widths as well) and then fit the lines (and continuum) and return the fitted line centers, widths, and amplitudes, etc. along with error estimates. It's been a while now since I used it, but as I recall, pyspeckit did not do all of those things. There may have been other reasons as well, but in the end I wrote my own fitting routines to work with the data. Am I wrong about the capabilities of pyspeckit?</div>

Emil and Jon - there is a package that fits exactly those requirements,<br>
called pyspeckit:<br>
<a href="http://pyspeckit.bitbucket.org" target="_blank">pyspeckit.bitbucket.org</a><br>
<br>
One of my major goals over the next year is to incorporate it into astropy<br>
bit by bit, i.e. make it work with astropy.models, astropy.units, and<br>
specutils. Only a little progress in that direction has been made (in part<br>
because my coding efforts have been focused more on astroquery).<br>
<br>
Emil - there is a scipy-dependent voigt profile implemented in pyspeckit.<br>
You can check that it agrees with yours:<br>

<br>
I'm bringing this up on this particular thread because I had considered<br>
submitting pyspeckit as a SOCIS project, but I think focusing on specutils<br>
instead will be better for the community. Nonetheless, there are some<br>
specific project ideas in place that may help support the case for a<br>
student working on specutils via SOCIS:<br>
