/* ** ** 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 60054.949109 0.000501 0.23128 0.00832 1.00000 0 52.86031 0.81830 49.28877 0.76301 12.22531 0.39702 11.39591 0.37009 60054.950116 0.000506 0.21808 0.00777 1.00000 0 55.66565 0.83819 51.97995 0.78268 12.13956 0.39191 11.33909 0.36605 60054.951120 0.000498 0.22757 0.00805 1.00000 0 54.43314 0.83533 51.02428 0.78302 12.38758 0.39494 11.61195 0.37021 60054.952095 0.000477 0.23623 0.00846 1.00000 0 54.22454 0.84971 50.82812 0.79649 12.80948 0.41278 12.00704 0.38692 60054.953059 0.000486 0.23055 0.00823 1.00000 0 55.00017 0.84741 51.35041 0.79118 12.68014 0.40837 11.83786 0.38122 60054.954129 0.000584 0.21953 0.00728 0.99831 0 55.63976 0.78301 51.83702 0.72942 12.21447 0.36657 11.38573 0.34174
