These directories contain the following:

fits_gamma_ray: For the less than 20 RHESSI gamma-ray flares, count spectrum and SRM FITS files at appropriate energy
        and time binning, as well as FITS files of suitable background for each flare.
		
fits_hires:  Count spectrum files for the larger RHESSI flares (events seen above 50 keV). Separate files are available 
        for each functional detector and include the orbit containing the flare (midnight-to-midnight), with 4s time 
        bins and native energy bins (channel boundaries specific to each detector segment). The corresponding
        (same energy binning) Spectral Response Matrix (SRM) files are also provided for each flare interval.

fits_standard:  Count spectrum files for every orbit of the RHESSI mission (midnight-to-midnight) with 4s bins, 77 energy
        bins 3-250 keV, combining all functional detectors. The corresponding (same energy binning) Spectral Response 
        Matrix (SRM) files are also provided for each flare interval.
        FITS files written by routine hsi_ar_sp_main.pro

flare_plots: PNG plot files in year/month/day directories
        Plots of count flux and photon flux spectra for each detector for each RHESSI flare
        Front detectors only
        Photon flux is computed using semi-calibrated option in spectrum object - this is a rough estimate of photon flux.
        Plots written by routines hsi_spectrum_mk_det_plots.pro, hsi_spectrum_check_dets.pro
        The file rhessi_flare_spectra.txt is used by Browser to determine the name of a flare plot file.

minute_plots: PNG plot files in year/month/day directories
        Plots of count flux spectrum for each detector for each minute of mission
        Front detectors only
        Plots written by routines hsi_min_spectra_plot.pro, hsi_spectrum_sepdet_plot.pro
		
        fits: FITS files organized in year/month/day directories for every orbit of RHESSI mission
           100 1-minute bins
           138 energy bins from 1.0 to 300.0 keV, .333 keV wide from 1 to 10 keV and then logarithmically spaced up to 300 keV
           Separate detectors (one file for each detector for each orbit)
           Front detectors only
           Thare are no corresponding DRM files.
           These FITS files are used to make the plots in the minute_plots directory.
           FITS files written by routines hsi_min_spectra_main.pro,  hsi_min_spectra_write_fits.pro

The flare plots and minute plots are useful for determining which detectors are good for that time interval.
The plots are shown in the RHESSI Browser when:
        for minute plots - Time-Based Quicklook / Per-min. det. spectra is checked
        for flare plots  - Flare-Based Quicklook / Peak det. spectra is checked

For a discussion on how to interpret the flare spectrum plots, please see the nugget titled
