**  Key:
**
**   BinCenter                - Center of time bin (MJD)
**   BinHW                    - One-half of the full time bin size (days)
**   Rate                     - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s).
**   RateError                - 1 sigma error in source count rate (cts/s)
**   FracExp                  - Conversion factor between bin size and observing time
**   Mode                     - 0 if in Windowed Timing (WT)
**                              1 if in Photon Counting (PC)
**   RawRate                  - Raw source count rate (cts/s)
**   RawError                 - 1 sigma error in the raw count rate (cts/s)
**   NetRate                  - Background subtracted count rate (cts/s)
**   NetError                 - 1 sigma error in the background subtracted count rate (cts/s)
**   BackRate                 - Background count rate (cts/s)
**   BackError                - 1 sigma error in the background count rate (cts/s)
**
**
**  Upper limits have an error listed as -1.00000.
