/* ** ** 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 59463.898026 0.000579 0.24098 0.02769 0.97500 0 4.69862 0.23793 4.07124 0.20615 1.13229 0.11679 0.98280 0.10137 59463.898940 0.000336 0.23586 0.03795 0.95690 0 4.36712 0.30544 3.75129 0.26236 1.03004 0.14927 0.88310 0.12798 59463.899600 0.000318 0.25048 0.03920 0.96364 0 4.50951 0.31486 3.85090 0.26882 1.12955 0.15818 0.96387 0.13497 59463.901026 0.001108 0.26403 0.02130 0.97389 0 4.72865 0.17389 4.02107 0.14787 1.24853 0.08964 1.05982 0.07609 59463.902450 0.000315 0.22739 0.03616 0.97248 0 4.81717 0.33401 4.10279 0.28446 1.09539 0.15679 0.93486 0.13383 59463.903144 0.000379 0.18945 0.02926 0.97710 0 4.82167 0.29929 4.13591 0.25670 0.91346 0.12920 0.78255 0.11067 59463.903868 0.000344 0.20481 0.03198 0.97479 0 4.86317 0.31281 4.18010 0.26883 0.99604 0.14172 0.85889 0.12221 59463.904539 0.000327 0.23367 0.03779 0.97345 0 4.47563 0.31317 3.79349 0.26543 1.04584 0.15250 0.88626 0.12924 59463.905181 0.000315 0.23090 0.03638 0.97248 0 4.82612 0.33508 4.09764 0.28451 1.11436 0.15760 0.94497 0.13364 59463.905824 0.000327 0.21927 0.03483 0.95575 0 4.92700 0.33006 4.16066 0.27872 1.08035 0.15561 0.91259 0.13144 59463.906582 0.000431 0.22704 0.03059 0.93289 0 5.07841 0.29029 4.31965 0.24693 1.15299 0.14066 0.98290 0.11990 59463.907667 0.000654 0.22403 0.02371 0.97788 0 5.24077 0.23671 4.46235 0.20154 1.17409 0.11235 0.99893 0.09560
