| 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. |

- Nancy Grace Roman Space Telescope: https://stsci.box.com/v/pandeia-refdata-v1p7v2p0-roman
Download and untar the files to a suitable location.

You CAN untar both sets of files to the same location and run calculations for Webb and Roman. 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. |
