Hi Emil,

I fully agree that PANDAS is the choice between sanity and madness as I've discovered a couple of months ago! I think as there are some other tools being developed now in matplotlib (thinking of Tom R's WCSAxes), it would be nice to stick to that. I'm not arguing that traits is a bad choice, just from a unifying standpoint matplotlib makes sense. 

It would be great to get some of your expertise on this mentor application. Interested?

Cheers,
   Wolfgang

It hooks directly up to a wrapper I've made for lmfit, but given the modularity, it should be relatively easy to change to other backends.

Maybe this ESA opportunity would work for that.  Like many others I have my own routines that I've written to do this, but they are neither general enough nor user-friendly enough to be widely usable.  I think that a focused effort on this could produce something that would be very helpful to many people.  The requirements would be (just off the top of my head):
>>> - gui interface, for example for placement of line centers
>>> - general methods for inputting data (fits, hdf5, ascii table)
>>> - robust fitting routines that return error bars on fitted parameters
>>> - a range of possible line shape functions (e.g. gaussian, lorentz, etc.) and continuum fitting
