Version Description¶
v1.0 - v1.4¶
The original IDL version of PAHFIT can be found in: http://tir.astro.utoledo.edu/jdsmith/research/pahfit.php. For more details and background of PAHFIT
, see the background page.
v2.0¶
Adopting the astropy.modeling framework, this version of python PAHFIT matches the capability of the IDL version. Also, the modular approach has been built-in for future contributions, e.g., science/instrument packs.
v2.1¶
PAHFIT v2.1 is an enhanced version of v2.0 that extends the fitting range down to the near IR at 2.5 µm (total wavelength coverage: 2.5–38 µm). The detail of this version is discussed in Lai et al. 2020, ApJ, 905, 55, in which the model was trained by a sample of 113 bright PAH galaxies drawn from the AKARI-Spitzer Extragalactic Spectral Survey (ASESS).
The summary of the newly added components and the instruction of running the AKARI-Spitzer combined spectrum can be found in: PAHFIT 2.1 summary
v2.2¶
Enhancement to support Infrared Space Observatory spectra
v2.3¶
Support the JWST simulated data
v2.4¶
Support the JWST observations
