The RHESSI Flare Image Archive, located in the flare_images_v2 directory, contains image cube FITS files that can be used with RHESSI image object software, converted to map structures via hsi_fits2map, or read by any standard FITS reader.

The MEM_GE algorithm applies the Maximum Entropy Method as developed by the Genoa group to reconstruct solar flare X-ray and gamma-ray images. This technique seeks the most uniform image consistent with the observed data, using entropy constraints to suppress noise and artifacts while preserving fine structure. MEM_GE produces smooth, high-quality images that are particularly effective for analyzing complex flare morphologies.

MEM_GE FITS files follow the naming convention hsi_imagecube_ge_YYYYMMDD_HHMM_xxxxx.fits, where YYYYMMDD and HHMM represent the observation date and start time (UTC), xxxxx indicates the bin size identifier, and .fits denotes the standard Flexible Image Transport System format.
