/* ** ** 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 58217.766375 0.000567 0.12062 0.02983 0.96939 0 1.98967 0.15860 1.68059 0.13394 0.23999 0.05619 0.20245 0.04740 58217.767315 0.000373 0.20398 0.05022 0.98450 0 1.85435 0.19108 1.55056 0.15976 0.37825 0.08458 0.31549 0.07054 58217.768102 0.000414 0.15110 0.03635 0.97902 0 2.22081 0.19690 1.88528 0.16715 0.33556 0.07503 0.28619 0.06399 58217.769008 0.000492 0.15316 0.03685 0.97647 0 1.87359 0.16640 1.57744 0.14008 0.28695 0.06417 0.24137 0.05397 58217.769966 0.000466 0.15535 0.03850 0.98137 0 1.91252 0.17399 1.59148 0.14479 0.29710 0.06850 0.24683 0.05690 58217.770842 0.000411 0.17471 0.04241 0.98592 0 1.97580 0.18669 1.63823 0.15480 0.34518 0.07719 0.28619 0.06399 58217.771754 0.000501 0.14129 0.03381 0.97110 0 2.01997 0.17220 1.68666 0.14377 0.28539 0.06382 0.23849 0.05333 58217.772790 0.000535 0.12533 0.03028 0.98919 0 2.06950 0.17099 1.72714 0.14269 0.25938 0.05889 0.21603 0.04904 58217.773747 0.000422 0.15766 0.03858 0.97260 0 2.12695 0.19412 1.76486 0.16108 0.33533 0.07613 0.27840 0.06320 58217.774607 0.000437 0.15286 0.03736 0.97351 0 2.16129 0.19059 1.80765 0.15940 0.33038 0.07530 0.27529 0.06277 58217.775715 0.000671 0.13205 0.02758 0.97414 0 2.09545 0.15053 1.74632 0.12544 0.27671 0.05427 0.23047 0.04520
