Abstract
pyspeckit
is a toolkit and library for spectroscopic analysis in Python. We describe the
pyspeckit
package and highlight some of its capabilities, such as interactively fitting a model to data, akin to the historically widely-used
splot
function in
IRAF
.
pyspeckit
employs the Levenberg–Marquardt optimization method via the
mpfit
and
lmfit
implementations, and important assumptions regarding error estimation are described here. Wrappers to use
pymc
and
emcee
as optimizers are provided. A parallelized wrapper to fit lines in spectral cubes is included. As part of the
astropy
affiliated package ecosystem,
pyspeckit
is open source and open development, and welcomes input and collaboration from the community.
