The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) recorded X-ray and gamma-ray data between 3 keV and 17 MeV from the Sun between February 2012 and April 2018. Please see the RHESSI web site at https://hesperia.gsfc.nasa.gov/rhessi for a complete description of the mission, the instrument, and the software needed to analyze the data. 

These directories contain the imagecube FITS files containing the images in the RHESSI Flare Image Archive (which is in the flare_images_v2 directory up one level from here).

These FITS files can be used as input to the RHESSI image object software, or read into an array of map structures using the routine hsi_fits2map, or read directly by a standard FITS reader.

for more explanation of how to use the imagecube FITS files.
