**
**  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)
**
**
**  Upper limits have an error listed as -1.00000.
