/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59304.331008 0.000310 0.26693 0.04249 0.98131 0 4.20886 0.30752 3.57938 0.26149 1.12346 0.15889 0.95397 0.13491 59304.332412 0.001094 0.27302 0.02193 0.97090 0 4.51740 0.16825 3.98184 0.14826 1.23332 0.08780 1.08588 0.07725 59304.334573 0.001068 0.27872 0.02244 0.97561 0 4.63710 0.17479 3.98046 0.15003 1.29245 0.09196 1.10700 0.07875 59304.335965 0.000324 0.26227 0.04229 0.98214 0 4.03553 0.29920 3.44396 0.25535 1.05841 0.15155 0.90084 0.12896 59304.336616 0.000327 0.20633 0.03174 0.96460 0 5.16652 0.32867 4.54180 0.28887 1.06599 0.14929 0.93734 0.13125 59304.337241 0.000298 0.21755 0.03536 0.99029 0 4.81979 0.32913 4.36745 0.29823 1.04855 0.15466 0.94995 0.14011 59304.337840 0.000301 0.23145 0.03695 0.99038 0 4.62730 0.31998 4.19425 0.29004 1.07100 0.15413 0.97076 0.13970 59304.338491 0.000350 0.21996 0.03181 1.00000 0 4.95745 0.30797 4.46978 0.27766 1.09043 0.14241 0.98438 0.12856 59304.339885 0.001045 0.26757 0.02314 0.95845 0 4.30535 0.17062 3.72010 0.14742 1.15197 0.08857 0.99503 0.07650
