/* ** ** 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 59018.068237 0.000550 0.23336 0.03715 0.99474 0 2.65688 0.18516 2.24226 0.15626 0.62002 0.08873 0.52448 0.07505 59018.069100 0.000312 0.16823 0.04032 0.98148 0 2.71702 0.25004 2.32819 0.21425 0.45709 0.10115 0.39198 0.08675 59018.069913 0.000501 0.25987 0.04086 0.96532 0 2.76520 0.19656 2.37298 0.16867 0.71860 0.10079 0.61757 0.08662 59018.070998 0.000584 0.21775 0.03461 0.95545 0 2.72133 0.18346 2.34659 0.15820 0.59258 0.08530 0.51092 0.07355 59018.072175 0.000593 0.25230 0.03983 0.98537 0 2.31326 0.16497 1.99482 0.14226 0.58363 0.08220 0.50322 0.07087 59018.073194 0.000425 0.29695 0.04856 0.97279 0 2.70769 0.21431 2.33453 0.18478 0.80405 0.11506 0.69319 0.09919 59018.074296 0.000677 0.22008 0.03156 0.96462 0 2.80160 0.17115 2.40812 0.14710 0.61658 0.07999 0.53021 0.06879
