/* ** ** 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 56409.091482 0.000440 0.23568 0.03746 0.97368 0 3.54251 0.24466 2.83406 0.19559 0.83491 0.11953 0.66984 0.09584 56409.092347 0.000420 0.34278 0.04838 0.95862 0 3.56626 0.25025 2.86792 0.20123 1.22246 0.14972 0.97965 0.11995 56409.093099 0.000333 0.30429 0.04935 0.99130 0 3.54887 0.28172 2.88718 0.22919 1.07987 0.15272 0.87865 0.12426 56409.093877 0.000446 0.21733 0.03416 0.98052 0 3.77989 0.25299 3.04440 0.20376 0.82147 0.11685 0.65995 0.09387 56409.094786 0.000463 0.20957 0.03273 0.96250 0 3.89421 0.25102 3.08758 0.19902 0.81611 0.11609 0.64709 0.09205 56409.095897 0.000648 0.24110 0.03111 0.96897 0 3.57488 0.20244 2.86750 0.16235 0.86192 0.09992 0.68987 0.07997 56409.157952 0.000431 0.20503 0.03178 0.96644 0 4.12617 0.26184 3.39656 0.21553 0.84601 0.11965 0.69560 0.09837 56409.158800 0.000417 0.27272 0.04312 0.94444 0 3.33971 0.24521 2.75288 0.20213 0.91082 0.12754 0.75125 0.10520 56409.159659 0.000443 0.23596 0.03736 0.96732 0 3.46855 0.24121 2.85739 0.19871 0.81842 0.11644 0.67329 0.09578 56409.160559 0.000457 0.23313 0.03675 0.98101 0 3.37803 0.23525 2.77826 0.19348 0.78752 0.11138 0.64624 0.09139 56409.161754 0.000732 0.26668 0.03211 0.98024 0 3.24344 0.17824 2.68651 0.14763 0.86498 0.09268 0.71655 0.07678
