Notes:

Solar flare identification strategy:   
  Using the daily CSPEC file,  we construct a measure of the net solar signal (called synthetic 
  rate below) by  
  1) subtracting the summed rates in the anti-sunward detectors from those in the sunward       
     detectors for two energy bands, 
  2) smoothing these two rates with a square wave to produce a value sensitive             
     to solar flares and multiplying them together, and 
  3) multiplying that value by the short wavelength (0.5 - 4 Å) flux seen with        
     the GOES soft X-ray sensor.  
  Time intervals with this measure of the solar flux greater than the value typical for a C2 flare are 
  identified as solar flares.    
  
Description of Columns:
  Flare -             Flare number constructed from start time of flare: yymmdd_hhmm where yy=year, mm=month, 
                      dd=day of month, hh=hour, and mm=minute, all two digits.
  Start time -        Time when the synthetic rate exceeds the level corresponding to a C2 flare
  Peak time -         Time of maximum rate in the 12-25 keV band
  End time -          Time when the synthetic rate became less than the level corresponding to a C2 flare
  Dur -               Duration of flare in seconds
  Peak rate -         Maximum rate in the 12-25 keV band in counts/sec
  Total counts -      Total counts in the 12-25 keV band
  Sunward Detectors - Four most sunward NaI detectors at the peak time (in 12-25 keV band) of the flare
  Trigger -           Fermi Trigger Designation if flare caused a trigger.  If there is more than one trigger 
                      during flare, this is the one nearest to the peak time.
  RHESSI Flare # -    The RHESSI flare designation if this flare was observed by RHESSI

The GBM flare catalog FITS file contains more information than displayed in this text listing, including:
  *  peak time, peak rate, total counts, and all NaI detector cosines at peak time for five energy bands: 
     6-12, 12-25, 25-50, 50-100, and 100-300 keV.
  *  all triggers within the duration of the flare.
