RHESSI Data

RHESSI Level-0 data files contain the full raw telemetry data in packed format.  Even though these files are in standard FITS format, they should be read only through the RHESSI SSW software due to the complicated unpacking algorithms.  The Level-0 files are large(~2 GB / day), and are broken up into ~15 orbit files per day.  They are consecutive; the start time of each file is given in the file name.  Because the RHESSI data consists of the time and energy of every photon, the software can bin the data from the Level-0 files into arbitrary time and energy bins selected by the user.  The Level-0 files are usually available within 8 hours after the observations were taken, with gaps filled in within a day or two.

The Observing Summary files are smaller daily FITS files (~2 MB / day) that contain various rates pre-binned to coarse energy and time resolution.  The files can be copied and read quickly, but there is no flexibility in accumulation options.  These files can be read by a standard FITS reader, but using the RHESSI SSW software will again provide the most benefit.

A flare list, quicklook time profile and image plots, and much more are generated on a daily basis.
