/* ** ** 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 57898.407747 0.000437 0.12891 0.03072 0.96689 0 2.49919 0.20579 2.13081 0.17546 0.32217 0.07204 0.27443 0.06136 57898.408624 0.000440 0.11586 0.02741 0.98684 0 2.71403 0.20973 2.30865 0.17840 0.31444 0.07032 0.26711 0.05973 57898.409399 0.000336 0.16058 0.03884 0.99138 0 2.57006 0.23664 2.17875 0.20059 0.41271 0.09229 0.34841 0.07791 57898.410047 0.000312 0.17777 0.04427 0.98148 0 2.42331 0.23484 2.07768 0.20135 0.43078 0.09883 0.36937 0.08474 57898.410756 0.000396 0.13814 0.03376 0.94161 0 2.56158 0.21574 2.19785 0.18511 0.35387 0.08118 0.30351 0.06963 57898.411520 0.000367 0.14463 0.03506 0.97638 0 2.57802 0.22271 2.20859 0.19080 0.37287 0.08445 0.31943 0.07235 57898.412298 0.000411 0.17319 0.03556 0.99296 0 2.68016 0.21530 2.29750 0.18456 0.46418 0.08772 0.39783 0.07518 57898.413103 0.000394 0.17496 0.04242 0.97059 0 2.04302 0.19137 1.74172 0.16314 0.35745 0.07993 0.30354 0.06787 57898.413832 0.000336 0.16772 0.04064 0.99138 0 2.42275 0.22595 2.07736 0.19373 0.40635 0.09086 0.34841 0.07791 57898.414480 0.000312 0.19559 0.04677 0.98148 0 2.36777 0.23165 2.03012 0.19861 0.46311 0.10106 0.39689 0.08661 57898.415134 0.000341 0.14115 0.03373 0.96610 0 2.90655 0.24524 2.49019 0.21011 0.41026 0.09174 0.35146 0.07859 57898.416419 0.000943 0.10452 0.01794 0.96933 0 2.68630 0.14141 2.29066 0.12057 0.28078 0.04586 0.23946 0.03911
