/* ** ** 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 54562.403877 0.000347 0.28001 0.04568 0.97500 0 3.92817 0.29691 3.06735 0.23004 1.09992 0.15904 0.84727 0.12124 54562.404534 0.000310 0.30194 0.04936 0.97196 0 3.86624 0.30571 3.15456 0.24943 1.16737 0.16704 0.95318 0.13639 54562.405234 0.000391 0.27406 0.04423 0.97778 0 3.43712 0.25640 2.75153 0.20521 0.94198 0.13480 0.75099 0.10746 54562.406039 0.000414 0.20415 0.03210 0.99301 0 4.23952 0.27622 3.42219 0.22294 0.86551 0.12387 0.69810 0.09989 54562.406782 0.000330 0.28735 0.04640 0.98246 0 3.84251 0.29365 3.09211 0.23631 1.10416 0.15707 0.88972 0.12656 54562.407454 0.000341 0.25356 0.04120 0.95763 0 4.26694 0.30757 3.39596 0.24477 1.08194 0.15754 0.86350 0.12578 54562.408128 0.000333 0.28505 0.04527 0.96522 0 4.01386 0.30079 3.24336 0.24304 1.14417 0.16023 0.92045 0.12889 54562.409097 0.000637 0.33336 0.03782 0.96101 0 3.75124 0.21037 3.00746 0.16864 1.25053 0.12334 1.00130 0.09875 54562.475489 0.000425 0.22538 0.03546 0.98639 0 3.96127 0.26672 3.12925 0.20985 0.89278 0.12697 0.69080 0.09769 54562.476698 0.000784 0.31741 0.03208 0.97048 0 3.90818 0.19315 3.11638 0.15399 1.24049 0.10938 0.98998 0.08727 54562.477847 0.000365 0.27810 0.04480 0.96825 0 3.73759 0.28248 2.93762 0.22202 1.03942 0.14786 0.81679 0.11619 54562.478620 0.000408 0.22630 0.03616 0.95745 0 4.07927 0.27569 3.21099 0.21701 0.92313 0.13367 0.72662 0.10521 54562.479334 0.000307 0.30590 0.04951 0.98113 0 4.01297 0.31576 3.14847 0.24774 1.22756 0.17360 0.96314 0.13621 54562.480014 0.000373 0.27134 0.04402 0.99225 0 3.62003 0.27082 2.83882 0.21238 0.98228 0.14139 0.77041 0.11089 54562.480767 0.000379 0.25844 0.04007 0.96947 0 4.20461 0.29158 3.31559 0.22993 1.08662 0.15068 0.85480 0.11854
