/* ** ** 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 59700.068312 0.000541 0.27606 0.02236 0.99465 0 8.51360 0.32060 7.73969 0.29143 2.35024 0.16855 2.13676 0.15322 59700.069513 0.000660 0.23669 0.01906 0.98187 0 8.17480 0.28678 7.45933 0.26168 1.93492 0.14023 1.76558 0.12796 59700.070795 0.000622 0.25141 0.02018 0.99070 0 8.13054 0.29351 7.42131 0.26791 2.04410 0.14657 1.86590 0.13380 59700.071998 0.000582 0.26568 0.02119 0.98507 0 8.36118 0.30772 7.63497 0.28099 2.22136 0.15720 2.02840 0.14354 59700.073135 0.000556 0.29398 0.02390 0.98958 0 7.79540 0.30275 7.11708 0.27640 2.29169 0.16366 2.09224 0.14942 59700.074316 0.000625 0.25967 0.02083 0.98611 0 7.87324 0.28754 7.18750 0.26250 2.04443 0.14600 1.86632 0.13328 59700.075473 0.000532 0.30280 0.02464 0.99457 0 7.91783 0.31056 7.22741 0.28348 2.39752 0.17091 2.18845 0.15601 59700.076544 0.000538 0.29111 0.02364 0.99462 0 8.13100 0.31768 7.39913 0.28909 2.36704 0.16848 2.15445 0.15335 59700.077687 0.000605 0.25260 0.02046 0.99043 0 8.27677 0.30060 7.52527 0.27330 2.09071 0.15133 1.90019 0.13752 59700.079070 0.000778 0.21126 0.01582 0.99628 0 8.54205 0.26808 7.79798 0.24473 1.80463 0.12265 1.64742 0.11197
