/* ** ** 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. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 55624.585058 0.000854 0.12203 0.00928 0.97627 0 12.29960 0.30540 11.29187 0.28033 1.50087 0.10782 1.38033 0.09915 55624.586759 0.000848 0.11801 0.00893 0.99317 0 12.70934 0.31267 11.56069 0.28440 1.49983 0.10738 1.36509 0.09771 55624.588388 0.000781 0.12575 0.00960 0.98519 0 13.08010 0.33207 11.82148 0.30010 1.64480 0.11847 1.48696 0.10709 55624.589971 0.000802 0.12045 0.00928 0.98556 0 13.10163 0.32593 11.92181 0.29657 1.57813 0.11505 1.43628 0.10472 55624.591594 0.000822 0.12455 0.00966 0.97183 0 12.54507 0.31703 11.35907 0.28705 1.56247 0.11460 1.41447 0.10377 55624.593267 0.000851 0.11355 0.00863 0.99320 0 13.11362 0.31652 11.92850 0.28791 1.48908 0.10727 1.35456 0.09756 55624.595034 0.000911 0.10980 0.00837 0.98413 0 12.67062 0.30061 11.57526 0.27461 1.39119 0.10084 1.27038 0.09206 55624.597184 0.001238 0.12483 0.00766 0.98832 0 12.53990 0.25569 11.50562 0.23458 1.56538 0.09058 1.43708 0.08314
