This includes all our analysis software as well as RST 3.2 beta-4 (which should be similar to the latest rst 3.3) and the THEMIS library. Instructions to install this package can be found on our website which links to this pdf guide: link)

DaViT has been developed on a Linux platform, and should in theory also work on MacOS, though I do not think we have ever tried. I do not believe this works on Windows though. Most of DaViT is written in IDL (with some fortran and C) and is fairly well documented (you can see the documentation on our website: link)
