PhoSim users- I have tagged and released version 3.2.1 of the photon simulator! This is a particularly stable and well-tested version that incorporates much of the development of this Fall. The major new features are: 1) Increased installation usability: a simplified installation (just configure & make), cleaner directory separation of code/data/binaries, etc. 2) Easier user interface: the phosim script has a number of command line switches (try out: phosim -h) & there are now meta-commands that encapsulate a number of more esoteric commands (i.e. clearturbulence) 3) Enhanced validation: we now have 83 validation metrics from the integration & unit tests that are run many times before releasing a version 4) Background photons are simulated as regular astrophysical photons (now faster & more fully tested) 5) Perturbation framework is implemented (the old perturbation model is still functioning, but once we get the camera & telescope data installed perturbations will be based on a physics finite element description) 6) Airglow has a spatial dependence (see the nice image that En-Hsin made below) 7) More documentation!: Our documentation is here: http://dev.lsstcorp.org/trac/wiki/IS_phosim The release notes associated with 3.2.1 is here: http://dev.lsstcorp.org/trac/wiki/IS_phosim_usability We have a walkthrough & installation guide for new users which you can follow here: https://confluence.slac.stanford.edu/display/LSSTDESC/phoSim+Walkthrough The easiest way to download a single version is to use this link: http://dev.lsstcorp.org/cgit/LSST/sims/phosim.git/refs/ Cheers, john ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the PHOSIM-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=PHOSIM-DEV&A=1
