/* ** ** 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 59629.005716 0.000871 0.29070 0.02409 0.98339 0 7.58316 0.29622 4.56085 0.17755 2.20440 0.16110 1.32172 0.09630 59629.007472 0.000885 0.25716 0.02028 0.98799 0 8.59148 0.30804 5.36131 0.19218 2.20939 0.15518 1.38052 0.09692 59629.735248 0.000570 0.28106 0.02301 0.98985 0 8.37898 0.32416 7.19401 0.27832 2.35496 0.16988 2.02273 0.14587 59629.736489 0.000671 0.23488 0.01854 0.98276 0 8.97431 0.30937 7.47843 0.25778 2.10786 0.14966 1.75698 0.12474 59629.737873 0.000712 0.22494 0.01790 0.98374 0 8.75711 0.29818 7.28144 0.24792 1.96979 0.14169 1.63816 0.11783 59629.739232 0.000648 0.26161 0.02091 0.98214 0 8.31900 0.30199 6.93694 0.25179 2.17629 0.15501 1.81615 0.12936 59629.740778 0.000897 0.26733 0.01821 0.99032 0 8.23524 0.25771 6.85692 0.21457 2.20154 0.13321 1.83245 0.11087
