| 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. |
...
In order to function, the Pandeia Engine requires one * set of reference data (containing instrument definitions):
...
Environment variable: $pandeia_refdata must point to the location of the top of the data file tree (the directory containing the VERSION_PSF file)*Both telescope datasets may be untarred to the same location to produce an engine that can work with either observatory; any files the two packages have in common may be overwritten.
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).
