In the past two weeks I got to know to SunPy. I learned about the modules (especially about SunPy Map and Sunpy IO) which will be important this summer. Besides that I spent time with understanding some IDL codes what can be used as a model for the first implementation of the proccess.
We have our new repo here: https://github.com/sunpy/xrayvision
At the moment it is empty (besides the module template), but soon this is going to change.
The first update will be a data structure which can represent the visibilities. For more info visit the issue.
