/* ** ** 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 59281.217590 0.000689 0.14271 0.01105 0.98739 0 12.76896 0.34849 11.72757 0.32008 1.82225 0.13203 1.67449 0.12133 59281.219025 0.000747 0.13585 0.01042 0.96899 0 12.62762 0.33014 11.62902 0.30403 1.71542 0.12369 1.57975 0.11390 59281.220636 0.000865 0.11531 0.00881 0.98997 0 12.60125 0.30661 11.60458 0.28236 1.45303 0.10524 1.33811 0.09692 59281.222300 0.000799 0.13063 0.00996 0.98188 0 12.15821 0.31442 11.19665 0.28956 1.58823 0.11396 1.46262 0.10494 59281.223834 0.000735 0.13352 0.01038 0.97638 0 12.81139 0.33612 11.79701 0.30951 1.71059 0.12517 1.57517 0.11526 59281.226169 0.001600 0.10819 0.00614 0.98373 0 13.01043 0.22912 11.98097 0.21099 1.40764 0.07594 1.29626 0.06993
