Installing the Pandeia Engine requires a python environment with the dependencies listed above, a set of telescope-specific datafiles, and an optional (but highly recommended) second set of data files for additional spectral manipulation capabilities.
...
Code Block | ||
---|---|---|
| ||
pip install pandeia.engine==3.2 |
or for Roman:
Code Block | ||
---|---|---|
| ||
pip install pandeia.engine==3.11.7 |
Warning |
---|
We highly recommend installing into a fresh python environment, such as ones provided by the Anaconda Python distribution, to avoid problems. If you experience issues after installing the Pandeia Engine, consider starting again with a fresh python installation and a clean new set of data files. |

- James Webb Space Telescope: https://stsci.app.box.com/v/pandeia-refdata-v1p7v3p2-jwst
- Nancy Grace Roman Space Telescope: https://stsci.box.com/v/pandeia-refdata-v1p7v3p1-roman
Download and untar the files to a suitable location.
Environment variable: $pandeia_refdata
must point to the location of the top of the data file tree (the directory containing the VERSION_PSF file)
Note | ||
---|---|---|
| ||
You CAN untar both sets of files to the same location and run calculations for Webb and Roman; where they have files in common, the files are identical and can be overwritten. VERSION_PSF is the only exception; . The sole difference between the packages are the jwst/ and roman/ directories (and the VERSION_PSF file, to reflect that Roman PSFs were regenerated with WebbPSF 1.0. |
...
, instead of WebbPSF 1.1). You can either untar the second telescope on top of the first one and overwrite any files when prompted, or copy just the second telescope's directory into the $pandeia_refdata location. |
Recommended Data
- An additional dataset: https://archive.stsci.edu/hlsp/reference-atlases can be used to provide more spectroscopic functionality (phoenix spectral models, normalization by HST bandpasses, among others).
