/* ** ** 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 58020.906202 0.000790 0.11260 0.02703 0.96703 0 3.23501 0.25043 1.33586 0.10334 0.36425 0.08276 0.14980 0.03399 58020.907606 0.000613 0.20783 0.05208 0.96226 0 2.30528 0.24411 0.93499 0.09896 0.47912 0.10881 0.19386 0.04399 58020.908780 0.000561 0.20797 0.05136 0.95876 0 2.55760 0.26704 1.03072 0.10756 0.53190 0.11903 0.21541 0.04817 58020.910134 0.000793 0.12438 0.03002 0.98175 0 2.91094 0.23654 1.19149 0.09680 0.36207 0.08228 0.14702 0.03336 58020.911477 0.000550 0.24398 0.06186 0.95789 0 2.35664 0.26258 0.91733 0.10213 0.57498 0.13096 0.22260 0.05068 58020.912935 0.000909 0.11315 0.02675 0.97452 0 2.93546 0.22482 1.15972 0.08874 0.33214 0.07430 0.13094 0.02928 58020.914588 0.000744 0.15005 0.03610 0.97276 0 2.80209 0.24729 1.07183 0.09449 0.42045 0.09410 0.16027 0.03584 58020.915979 0.000648 0.22982 0.05329 0.95536 0 2.41827 0.24461 0.92511 0.09354 0.55577 0.11596 0.21531 0.04490
