Thought you might be interested that PhoSim v5.4 is completed. All of the details are available following links at the main PhoSim site:
https://bitbucket.org/phosim/phosim_release/wiki/Home
Some highlights from PhoSim v5.4 include: detailed photon-cloud interactions, detailed physics improvements on turbulence representations, additional polynomial surface perturbation capabilities, simplication and generalization of instrument & site characteristics (ISC), capabilities for individual coating & electrical properties for individual sensors, reduction in the number of required ISC files,expansion of blooming/midline capabilities, various improvements in optimizations for different telescopes, and general increase in the speed of simulations. There have been more tutorials added and more updates to documentation as well.
In addition, if you don’t want to run PhoSim yourself, PhoSim data is being continually produced for the PhoSim Rubin Survey (PRS) that you can download through the links above. We will switch to a new version soon.
