Walk through

You can install Gen TSO from PyPI with the following command:

pip install gen_tso

Instrument and mode selection

To use pandeia you would need to download some files as per their documentation.

Target selection

First you need to download the pandeia reference data (version 3.0) from this folder: https://stsci.app.box.com/v/pandeia-refdata-v3p0-jwst

Detector setup

Unpack the file and set the $pandeia_refdata environment variable pointing to the top folder of the data (the directory containing the VERSION_PSF file).

Stellar atlases:

Then, you need to download these three reference stellar and calibration files, for example with these commands:

run.sh
wget https://archive.stsci.edu/hlsps/reference-atlases/hlsp_reference-atlases_hst_multi_kurucz-1993-atlas_multi_v2_synphot4.tar
wget https://archive.stsci.edu/hlsps/reference-atlases/hlsp_reference-atlases_hst_multi_pheonix-models_multi_v3_synphot5.tar
wget https://archive.stsci.edu/hlsps/reference-atlases/hlsp_reference-atlases_hst_multi_everything_multi_v15_sed.tar

Unpack these files and set the environment variable: $PYSYN_CDBS pointing to the trds directory.

Vega reference SED:

Lastly, you need to download the Vega reference spectrum:

wget https://ssb.stsci.edu/trds/calspec/alpha_lyr_stis_010.fits
