Pyspeckit: Lessons learned from a spectroscopic toolkit from pre-astropy to now
Pyspeckit is a toolkit for the analysis of already-reduced spectra. It grew out
of a need to do a really simple task, fitting a gaussian to part of a spectrum,
and mild rage against the old tools that were inadequate for various reasons.
Pyspeckit was not the only tool of its type created at the time, but it was
among the first in its class and is still in widespread use. Since it was
started before astropy, the package has undergone slow but significant internal
changes to keep up with the astropy environment. I will present a developer's
perspective on developing and maintaining the toolkit and some viewpoints on
the astronomer community using it.
