**  Swift/XRT hardness ratio for Mrk 421.
**  Hardness ratio for this file has been calculated by splitting the data at 2.0 keV.
**
**  Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/
**
**  When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949.
**
**  Key:
**
**   BinCenter      - Center of time bin (MJD).
**   BinHW          - One-half of the full time bin size (days).
**   FracExp        - Conversion factor between bin size and observing time.
**   Ratio          - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV).
**                    This is also Rate2/Rate1 from the following columns.
**   RatioError     - 1 sigma error in the hardness ratio.
**   Mode           - 0 if in Windowed Timing (WT).
**                    1 if in Photon Counting (PC).
**   Rate1          - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band.
**   RateError1     - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band.
**   NetRate1       - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band.
**   NetError1      - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band.
**   Rate2          - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band.
**   RateError2     - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band.
**   NetRate2       - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band.
**   NetError2      - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band.
**
**
**  Upper limits have an error listed as -1.00000.
