Software Downloads

Three software downloads are available; the AmesPAHdbIDLSuite, the AmesPAHdbPythonSuite and pyPAHdb, which significantly extend the tools available online. Their development is done on GitHub and comprehensive guides on installing and using these software can be found via the Documentation Portal.

AmesPAHdbIDLSuite

The AmesPAHdbIDLSuite is a collection of classes utilizing IDL^*'s object programming capabilities and can be used to work with downloaded database XML-files offline on your own machine.

Repository — Documentation

^*IDL is registered by NV5

AmesPAHdbPythonSuite

The AmesPAHdbPythonSuite is a Python package to work with downloaded database XML-files offline on your own machine.

Repository — Documentation

pyPAHdb

pyPAHdb is a Python package specifically aimed at fitting and decomposing astronomical PAH emission spectra and is being developed as part of the awarded James Webb Space Telescope (JWST) Early Release Science (ERS) program titled "Radiative Feedback from Massive Stars as Traced by Multiband Imaging and Spectroscopic Mosaics" (ID: 1288).
