Hi everyone, Now that yt development has moved to github, I want to bring up an opportunity for some smaller yt-related development projects. As some of you may know, it was decided a couple months ago that most of the code in the analysis_modules directory will be moved to various external repositories to allow them to be developed separately from the main yt codebase. The rough timeline for this is to have all analysis modules marked as deprecated by the release of yt-3.4 and fully removed (and in a separate, pip-installable repo) by yt-4.0. The initial extraction of the analysis modules has now been done and can be found here: https://github.com/yt-project/yt_astro_analysis To be clear, the analysis modules are still present in yt, but this repo contains only those modules. The revision history has also been maintained. Anyway, there are a number of small tasks that must be completed before this package becomes the replacement for yt's analysis modules. I will begin adding issues on github for all these. If anyone is interested in helping out with this, just come talk to me on the yt slack channel or feel free to just dig in and start issuing PRs. Thanks! Britton
