AtomDB Charge Exchange Model (ACX)

The AtomDB team is happy to announce the release of the first AtomDB Charge Exchange (acx) model suite. This is version 1.0.1, released June 26th 2015. The code works in XSPEC and ISIS, enabling CX modeling along the lines of that described in Smith et al. 2012. More detailed papers describing these models have either been submitted or are near to submission. Installation and usage instructions are also included in the tarball.

Note that version 1.0.1 contains minor fixes to the stand alone DACX code. If you have been using the ACX model within XSPEC you will notice no difference, and there is no need to update previous results.
