Orion Bar synthetic spectra

README

MIR and NIR spectra of five regions

Enhanced data products

Highly processed data products

We will provide highly processed data, in particular stitched IFU cubes.

Maps of spectral features (SEP1)

FITS files of integrated line and band maps using PAHFIT (see below).

Template spectra from the key regions (SEP2)

Template spectra of HII region, ionized front, dissociation front, and molecular zone, extracted from the observations by blind signal separation methods.

Products facilitating data reduction and processing

Spectral order stitching and stitched cubes (SEP3)

We will quantify any spectral stitching issues.

Cross-calibration of spectra and images (SEP4)

We will provide color corrections for fields with bright PAH bands and quantify contributions of specific lines and PAH bands to photometric bands.

PAHFIT (SEP5)

This tool decomposes a spectrum into gas lines, dust features and dust continuum components. We will extend its capabilities to include JWST applicability.

Line list (SEP6)

List of all lines and bands present in the data.

Data-interpretation tools

H2 fitting tool (SEP7)

It will provide fits of observed  H2 excitation diagrams. This is part of the PDR Toolbox.

The interstellar medium database: ISMDB (SEP8)

A model database with a web-based fitting tool, giving an access to model grids from the Meudon PDR code and the KOSMA-τ PDR code.

PAHdb spectral analysis tools (SEP9)

A tool to decompose a PAH emission spectrum into contributing sub-populations.

https://github.com/PAHdb/pyPAHdb

Ionized gas lines diagnostic diagrams (SEP10)

We will provide diagnostic diagrams of key species to be observed with JWST for the interpretation of ionized gas lines and its conversion into physical conditions and extinction. This is part of PDR toolbox.
