/* ** ** 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 59760.021351 0.000495 0.29914 0.02444 0.99415 0 8.69997 0.34091 7.78675 0.30509 2.60250 0.18658 2.33065 0.16707 59760.022367 0.000521 0.29074 0.02377 0.98333 0 8.57836 0.33080 7.66755 0.29568 2.49406 0.17977 2.22841 0.16062 59760.023423 0.000535 0.27432 0.02218 0.97838 0 8.86308 0.33174 7.98297 0.29879 2.43130 0.17429 2.18901 0.15691 59760.024508 0.000550 0.25792 0.02071 0.98947 0 9.25689 0.33810 8.19082 0.29912 2.38756 0.17069 2.11225 0.15100 59760.025599 0.000541 0.26418 0.02128 1.00000 0 8.94086 0.33193 8.04431 0.29863 2.36203 0.16885 2.12354 0.15180 59760.026667 0.000527 0.27990 0.02239 0.98352 0 8.98446 0.33869 8.04289 0.30315 2.51476 0.17739 2.24955 0.15867 59760.027717 0.000524 0.29590 0.02394 0.98895 0 8.48584 0.33042 7.55182 0.29404 2.51096 0.17804 2.23338 0.15835 59760.028817 0.000576 0.23684 0.01883 0.99497 0 9.48706 0.32998 8.47307 0.29470 2.24689 0.16065 2.00557 0.14337 59760.030214 0.000822 0.21387 0.01518 0.98239 0 9.11900 0.27046 8.20191 0.24326 1.95028 0.12576 1.75440 0.11312
