/* ** ** 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 58262.148371 0.000388 0.14709 0.03576 0.98507 0 2.41047 0.21280 2.03392 0.17951 0.35456 0.08032 0.30002 0.06796 58262.149318 0.000558 0.13073 0.03114 0.96891 0 1.94299 0.15952 1.63697 0.13440 0.25401 0.05680 0.21426 0.04791 58262.150336 0.000460 0.13009 0.03099 0.98742 0 2.37444 0.19526 1.96015 0.16119 0.30889 0.06907 0.25520 0.05706 58262.151227 0.000431 0.15560 0.03789 0.97987 0 2.07689 0.18550 1.74321 0.15567 0.32316 0.07320 0.27125 0.06145 58262.152208 0.000550 0.13464 0.03210 0.97368 0 1.92083 0.15872 1.60380 0.13253 0.25862 0.05783 0.21658 0.04843 58262.153287 0.000530 0.12072 0.02931 0.97268 0 2.16610 0.17188 1.82570 0.14485 0.26149 0.06001 0.21987 0.05047 58262.154141 0.000324 0.23588 0.05677 0.99107 0 2.00576 0.21387 1.67328 0.17840 0.47311 0.10208 0.39287 0.08476 58262.154778 0.000312 0.21431 0.05293 0.97222 0 2.13815 0.22418 1.78036 0.18667 0.45823 0.10247 0.38159 0.08533 58262.155385 0.000295 0.18211 0.04489 0.99020 0 2.53566 0.24641 2.15568 0.20948 0.46177 0.10461 0.39210 0.08882 58262.156007 0.000327 0.19268 0.04823 0.97345 0 2.18727 0.21830 1.84770 0.18439 0.42144 0.09673 0.35579 0.08167 58262.156629 0.000295 0.18873 0.04676 0.99020 0 2.49429 0.25014 2.07236 0.20784 0.47076 0.10666 0.39210 0.08882 58262.157249 0.000324 0.19309 0.04594 0.94643 0 2.44766 0.23182 2.05421 0.19455 0.47262 0.10314 0.39689 0.08661 58262.158299 0.000726 0.12759 0.02515 0.97610 0 2.30815 0.15176 1.93639 0.12730 0.29449 0.05474 0.24590 0.04568
