Reprojection of events seen along the Earth-Sun line to the STEREO POV #187

Open wafels opened 7 years ago

wafels commented 7 years ago

Currently all the events shown in Helioviewer are from the HEK, and so are seen from along the Earth-Sun line. These events should be re-projected when STEREO data is shown.

This problem is now solved in SunPy, and was tested on the Python command line using SunPy 0.9.5. A solution to this issue would be to pass the HEK co-ordinates to SunPy to do the re-projection. Some effort should be expended in understanding how to interface SunPy's coordinate system infrastructure with helioviewer. SunPy may be able to supply a number of useful features for helioviewer.org.

It would be nice in SunPy to have better support for HEK events. This would make it easier for Helioviewer to reproject events.

The code to do this is now in SunPy.

Need a module on visibility to make sure the reprojected event is indeed visible from the new POV.
