/* ** ** 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 59672.140936 0.000975 0.31701 0.02638 0.94955 0 11.47852 0.46682 3.91314 0.15728 3.63881 0.26416 1.23747 0.08876 59672.142232 0.000321 0.30646 0.05111 0.93694 0 10.02619 0.79676 3.05643 0.24282 3.07259 0.45054 0.93293 0.13677 59672.142906 0.000353 0.27437 0.04143 0.95902 0 12.03473 0.85153 3.57315 0.25276 3.30199 0.44046 0.97968 0.13063 59672.143583 0.000324 0.29311 0.04881 0.98214 0 9.81720 0.77610 3.02383 0.23906 2.87751 0.42171 0.88204 0.12931 59672.144700 0.000793 0.28649 0.02904 0.95985 0 11.23877 0.54089 3.42867 0.16498 3.21981 0.28718 0.97994 0.08739 59672.145794 0.000301 0.31917 0.05233 0.97115 0 10.23302 0.84855 3.10256 0.25725 3.26607 0.46193 0.99175 0.14025 59672.146465 0.000370 0.22500 0.03611 0.96094 0 11.66878 0.80581 3.55528 0.24545 2.62553 0.38033 0.79733 0.11548 59672.147157 0.000321 0.27898 0.04472 0.97297 0 10.77498 0.81291 3.32329 0.25072 3.00596 0.42511 0.92747 0.13116 59672.147799 0.000315 0.28219 0.04592 0.92661 0 11.21048 0.85012 3.45256 0.26182 3.16354 0.45553 0.97620 0.14054 59672.148433 0.000318 0.26210 0.04274 0.91818 0 11.93459 0.87311 3.68576 0.26965 3.12805 0.45584 0.96583 0.14073 59672.149703 0.000952 0.30316 0.02769 0.97264 0 10.77111 0.47342 3.30432 0.14521 3.26539 0.26149 1.00081 0.08013
