Tools for analysis and modeling of IR spectra
Spectools_ir is a small suite of tools designed for analysis of medium/high-resolution IR molecular astronomical spectra. It consists of three main sub-modules (flux_calculator, slabspec, and slab_fitter) as well as a 'utils' sub-module, with a few additional functions.
Spectools_ir was written with infrared medium/high-resolution molecular spectroscopy in mind. It often assumes spectra are in units of Jy and microns, and it uses information from the HITRAN molecular database. Some routines are more general, but users interested in other applications should proceed with caution.
Users are requested to let the developer know if they are using the code in spectools_ir. The code has been tested for only a few use cases, and users utilize at their own risk.
Requires internet access to utilize astroquery.hitran and access HITRAN partition function files.
Requires several standard scientific packages, as well as astropy, astroquery, corner, and emcee.
flux_calculator is a set of python codes to compute line fluxes from an IR spectrum.
slabspec is a set of python codes to produce LTE slab model emission spectra of molecules using the HITRAN database.
slab_fitter is a set of python codes to perform MCMC slab model fits to line fluxes using "emcee" (Foreman-Mackey et al. 2013; https://github.com/dfm/emcee; https://emcee.readthedocs.io/en/stable/) with flat priors.
utils contains some useful utility functions, including functions specific to JWST MIRI-MRS.
