/* ** ** 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 59811.927214 0.001152 0.21481 0.01699 0.97487 0 5.90150 0.19559 4.74866 0.15736 1.26771 0.09105 1.01915 0.07320 59811.928664 0.000298 0.20478 0.03213 0.98058 0 6.02785 0.39317 4.80079 0.31309 1.23440 0.17617 0.98434 0.14045 59811.929286 0.000324 0.21382 0.03180 0.99107 0 5.78280 0.36275 4.66795 0.29283 1.23648 0.16674 0.99264 0.13385 59811.930701 0.001091 0.22221 0.01775 0.98143 0 5.93233 0.20118 4.78853 0.16239 1.31820 0.09532 1.06267 0.07684 59811.932200 0.000408 0.21804 0.02920 0.98582 0 5.62354 0.32100 4.54032 0.25912 1.22614 0.14856 0.98908 0.11984 59811.932935 0.000327 0.20650 0.03239 0.97345 0 5.36662 0.34964 4.37671 0.28514 1.10821 0.15812 0.90381 0.12896 59811.933600 0.000339 0.20042 0.03122 0.99145 0 5.33099 0.34820 4.31302 0.28172 1.06844 0.15111 0.86351 0.12212 59811.934277 0.000333 0.21180 0.03239 0.96522 0 5.47708 0.35274 4.42601 0.28497 1.16004 0.16088 0.93850 0.13015 59811.934934 0.000324 0.17627 0.02710 0.99107 0 6.32689 0.38139 5.11940 0.30860 1.11526 0.15773 0.90240 0.12762 59811.935681 0.000422 0.21034 0.02823 0.96575 0 5.65689 0.31686 4.61132 0.25829 1.18990 0.14511 0.96975 0.11826
