Pardon Our Dust!
The latest release of the Pandeia engine is 1.5.1.
- the latest engine release is installable via pip
- The engine requires further telescope-specific data files to operate. See its installation instructions (Webb-specific) for more details and the rest of the software stack

Next Planned Release
Important
Version 1.5.2 is planned to release in late August 2020.
Highlights include:
- Users will no longer need the pysynphot data files to specify sources normalized in Vegamags
- Additional readout pattern for the NIRSpec Target Acquisition mode

question: do we need a separate fields for engine release notes & engine known issues? so far we have been doing laborious manual work to do this at release time. Yes, we think we do.
What support is available?
Nice carefully crafted statement about level of support
What is the Pandeia Engine?
The Pandeia engine uses a pixel-based 3-dimensional approach to perform calculations on small (typically a few arcseconds) 2-dimensional user-created astronomical scenes. It models both the spatial and the wavelength dimensions, using realistic point spread functions (produced using WebbPSF) for each instrument mode. It natively handles correlated read noise, inter-pixel capacitance, and saturation. Since the signal and noise are modeled for individual detector pixels, the ETC is able to replicate many of the steps that observers will perform when calibrating and reducing their JWST data. This simplifies interpretation of the extracted signal-to-noise ratio (SNR) calculated by the ETC.
Details on the algorithms used to compute signal and noise on the detector and the strategies used to compute the extracted products can be found in Pontoppidan et al. 2016.
