/* ** ** 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 58935.350109 0.000508 0.28254 0.07125 1.00000 1 3.59339 0.42240 0.83101 0.09767 1.01527 0.22652 0.23509 0.05245 58935.351009 0.000392 0.28666 0.07349 0.92593 1 4.77467 0.56752 1.09889 0.13062 1.36869 0.31087 0.31542 0.07163 58935.351721 0.000320 0.53648 0.15031 1.00000 1 2.94590 0.49732 0.67754 0.11438 1.58041 0.35339 0.36364 0.08131 58935.352607 0.000566 0.22770 0.05674 0.94872 1 4.12810 0.43938 0.94434 0.10052 0.93995 0.21180 0.21467 0.04837 58935.353842 0.000668 0.20845 0.04996 0.95652 1 3.99375 0.39574 0.91554 0.09071 0.83250 0.18167 0.19091 0.04166 58935.355018 0.000508 0.25200 0.06018 0.94929 1 4.59251 0.49410 1.05108 0.11309 1.15733 0.24675 0.26486 0.05647
