A set of DEM inversion software has been made available on Solarsoft under directory $SSW/packages/dem_sites. The software is based on new methods developed at Aberystwyth, and recently published in Solar Physics:

The first paper describes the core inversion method:

The second paper provides a gridding method that greatly increases the computational speed:

The software has currently only been tested on AIA/SDO for non-flare conditions, but should work with any instrument given measurements, errors, and temperature response functions.
