Announcing: yt 2.5.4
by Matthew Turk 02 Jul '13

02 Jul '13

Hi all, We're proud to release yt version 2.5.4. This is a scheduled point release that includes all bug fixes identified and fixed since the release of 2.5.3 on June 3. Additions, changes and bug fixes include: * Considerably (10x+) faster kD-tree building for volume rendering * System build fix for POSIX systems * Fixing domain offsets for halo centers-of-mass * Removing some Enzo-specific terminology in the Halo Mass Function * Addition of coordinate vectors on volume render * Updating RADMC3D export code to support FLASH * Pickling fix for extracted regions * Addition of some tracer particle annotation functions * Better error message for "yt" command * Fix for radial vs poloidal fields * Piernik 2D data handling fix * Fixes for FLASH current redshift If you are using the stable branch of yt from an installation script, you can upgrade using "yt update" or "yt update --all" to upgrade your full dependency stack. If you are using the development branch, you may already have these fixes. A tarball of this release has been uploaded to the Python Package Index (PyPI). While originally a 2.5.4 release was not planned, developments for 2.6 have been delayed. The next scheduled release will be on August 1, and will be version 2.6. We are hoping to include a unification of the Boxlib frontends, compatibility with Python 3 (and embedding inside Blender) and other usual improvements to the yt codebase. Documentation for this release can be found at: http://yt-project.org/docs/dev/ Thanks very much, Matt, on behalf of the yt development team

Analysis of projected quantities
by Harald Braun 01 Jul '13

01 Jul '13

Hi all, I'd like to do some analysis on projected quantities (or column densities) and quantities derived from those, like ratios etc. How can I use the output of some projections to derive some other quantities from it? How can I use those as inputs for BinnedProfileXd()-stuff, to compute profiles and phase plots? This would be extremely useful for analyzing my disk galaxy simulations. Thanks for your help. Best. Harald
