This software makes use of the ammonia model code found in pyspeckit by Adam Ginsburg & Jordan Mirocha and contributors. The Python implementation in pyspeckit was originally based on the IDL program nh3fit by Erik Rosolowsky, described in Rosolowsky et al. (2008).
The implementation of the fast exponential function is taken from the LIME radiative transfer code developed by Christian Brinch and the LIME development team. These modified files (fastexp.h, fastexp.c) are licensed under the GNU GPL v3.
