/* ** ** 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 59796.015700 0.000295 0.24233 0.03829 0.99020 0 6.12675 0.43066 4.11177 0.28892 1.48467 0.21011 0.99175 0.14025 59796.017092 0.001097 0.24893 0.01989 0.97361 0 6.23070 0.22196 4.32154 0.15390 1.55101 0.11092 1.07604 0.07692 59796.018825 0.000637 0.25095 0.02809 0.96029 0 5.65549 0.28477 3.83982 0.19330 1.41923 0.14187 0.96457 0.09639 59796.083632 0.000848 0.24458 0.01957 0.97611 0 6.28640 0.22357 5.67551 0.20182 1.53750 0.11022 1.38600 0.09934 59796.085290 0.000810 0.25173 0.02015 0.98929 0 6.29862 0.22762 5.69658 0.20586 1.58555 0.11326 1.43489 0.10250 59796.086977 0.000877 0.23065 0.01848 0.98020 0 6.42154 0.22317 5.75999 0.20015 1.48115 0.10690 1.32748 0.09580 59796.089061 0.001207 0.23260 0.01560 0.98321 0 6.58359 0.19208 5.95653 0.17378 1.53133 0.09249 1.38575 0.08370
