/* ** ** 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 56515.027652 0.001094 0.26905 0.02170 0.98148 0 4.61146 0.17075 3.96745 0.14690 1.24069 0.08892 1.06735 0.07650 56515.029785 0.001039 0.28627 0.02298 0.97772 0 4.61234 0.17441 3.98176 0.15056 1.32037 0.09352 1.13983 0.08073 56515.031124 0.000301 0.24014 0.03806 0.97115 0 4.75591 0.33109 4.10400 0.28570 1.14210 0.16261 0.98596 0.14037 56515.031842 0.000417 0.25055 0.03414 0.97917 0 4.52334 0.27595 3.90345 0.23813 1.13334 0.13810 0.97796 0.11916 56515.033158 0.000900 0.31940 0.02617 0.96141 0 4.80538 0.19085 4.14683 0.16469 1.53486 0.11000 1.32437 0.09492 56515.034362 0.000304 0.24418 0.03908 0.99048 0 4.51278 0.32150 3.89719 0.27764 1.10191 0.15794 0.95189 0.13644 56515.035586 0.000920 0.32872 0.02701 0.97799 0 4.50606 0.18314 3.88468 0.15788 1.48125 0.10580 1.27703 0.09121 56515.036830 0.000324 0.27049 0.04263 0.99107 0 4.11797 0.29872 3.55401 0.25781 1.11389 0.15586 0.96101 0.13447 56515.037666 0.000512 0.28798 0.03337 0.98870 0 4.47668 0.24555 3.86017 0.21174 1.28918 0.13157 1.11184 0.11347
