Calculate the Differential Emission Measure (DEM) from solar data using regularized inversion in SSWIDL.
For notes on the maths behind what the code is doing see pdf in notes/.
Note that this repo contains 3 versions of the DEMReg code:
- Original sswidl version from Hannah & Kontar (2012) which takes a single set of data (pixels, lines etc) for any instrument (just need to supply temperature response) in idl_org/
- Update of sswidl mapping version from Hannah & Kontar (2013) which can do any form of data (maps, single pixels) and for any instrument (just need to supply temperature response), in idl/
- Python version based off of idl/ which again can take any data format and any instrument, in python/
The two sswidl versions should give similar results but the mapping version will be quicker.
The all versions of code here should be the most up to date, including bug and typo fixes.
