The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) recorded X-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 RHESSI mission archive products that should facilitate analysis of RHESSI observations now and in the future. The primary Level-0 and quicklook archive is located here. (please read the aa_readme_hessidata file there for descriptions of those files).
These directories contain the following files:
detector_health | The detector health database records the status of the 18 RHESSI detector segments on a daily basis for the entire mission. Monthly plots showing the status for all detector segments for each day are in this directory. The information is also stored in .csv (comma separated value) files, one per detector segment per year, in the SSW software distribution in $SSW/hessi/dbase/det_health. Please see the readme for more details. | ||||||||||
eventlist_fits_v2 | Eventlist FITS files for each flare time interval containing time and energy information for every photon detected by RHESSI between 3.0 and 310.0 keV. These files were made during the creation of the flare image archive. Each file corresponds to one flare in the image archive. The eventlist FITS files are only useful if used within the SSWIDL RHESSI software. They contain unpacked detector event data and can be used as input to the image or spectrum object instead of the Level-0 files, saving time and the need to download the large Level-0 files. | ||||||||||
flare_images_v2 | Flare Image Archive. Images and related products were generated for >75,000 RHESSI flares (all identified flares that had sufficient counts, and whose position could be determined) using six image reconstruction methods. Please see the RHESSI Image Archive Strategy for information on how the parameters for imaging, including the time and energy bins, were chosen. Please see Guide to RHESSI Image Archive for an explanation of how to access the archive, and a detailed description of each type of plot shown in the archive. | ||||||||||
gamma_ray_templates | Gamma-ray templates for fitting spectra in OSPEX. | ||||||||||
goesplots | GOES lightcurve plots (daily, 12 hr, and orbital) and GOES event listings. | ||||||||||
imagecube_fits_v2 | Imagecube FITS files containing the images in the RHESSI Flare Image Archive. | ||||||||||
sff | Solar Flare Finder (cross-mission synoptic) plots. Please see Solar Flare Finder Document for more information. | ||||||||||
spectra |
| ||||||||||
spectrograms | Spectrograms of every front detector for every RHESSI orbit in 4s time bins, 39 energy bins from 3-270 keV, in both counts and count flux units. The spectrum FITS files created to make these plots are also available here. | ||||||||||
visibility_fits_hires_v2 | High time and energy resolution visibility FITS files fir each flare in the RHESSI Image Archive: 8s time resolution, up to 20 energy bins depending on the energy of the flare. All functional detector (front segments only) are used. | ||||||||||
visibility_fits_v2 | Visibility FITS files with the same time bins, energy bins, and detector selection as the images in the RHESSI Image Archive. |
