/* ** ** 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 55411.010111 0.000402 0.28103 0.04541 0.96403 0 3.08084 0.23091 2.63237 0.19730 0.86581 0.12395 0.73953 0.10586 55411.011005 0.000492 0.20842 0.03260 0.98824 0 3.35184 0.21784 2.85156 0.18531 0.69857 0.09940 0.59305 0.08438 55411.012119 0.000622 0.15068 0.02299 0.97209 0 3.69976 0.20404 3.16058 0.17430 0.55748 0.07932 0.47671 0.06783 55411.013143 0.000402 0.24579 0.03998 0.97122 0 3.48051 0.24879 2.97451 0.21263 0.85547 0.12500 0.72910 0.10649 55411.014002 0.000457 0.21197 0.03364 0.98101 0 3.53356 0.23565 2.99802 0.19993 0.74900 0.10788 0.63589 0.09159 55411.014943 0.000483 0.19701 0.03068 0.95808 0 3.72826 0.23614 3.15583 0.19989 0.73450 0.10450 0.62270 0.08860 55411.015837 0.000411 0.24061 0.03799 0.97183 0 3.53725 0.24827 3.01716 0.21176 0.85109 0.12037 0.72585 0.10265 55411.016818 0.000570 0.19073 0.02965 0.97462 0 3.20270 0.20043 2.71724 0.17003 0.61085 0.08692 0.51892 0.07383 55411.017891 0.000503 0.18381 0.02864 0.97701 0 3.73910 0.22962 3.17624 0.19504 0.68730 0.09840 0.58293 0.08345 55411.019066 0.000671 0.17459 0.02679 0.96983 0 3.00931 0.17909 2.54704 0.15157 0.52541 0.07431 0.44519 0.06296 55411.020278 0.000541 0.20327 0.03176 0.97326 0 3.15746 0.20398 2.68511 0.17347 0.64180 0.09132 0.54743 0.07789 55411.021853 0.001033 0.18990 0.02150 0.98039 0 3.35672 0.15178 2.81831 0.12742 0.63743 0.06618 0.53498 0.05554
