/* ** ** 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 56808.936157 0.000700 0.34385 0.02882 0.98760 0 7.75584 0.33089 4.78312 0.20348 2.66684 0.19242 1.65473 0.11894 56808.937586 0.000729 0.33146 0.02772 0.95635 0 7.72580 0.31788 4.91209 0.20210 2.56079 0.18645 1.62378 0.11826 56808.939030 0.000715 0.33519 0.02791 0.96761 0 7.58554 0.31483 4.93460 0.20481 2.54259 0.18351 1.65443 0.11939 56808.940520 0.000775 0.32643 0.02690 0.98134 0 7.27361 0.29835 4.64478 0.19049 2.37432 0.16967 1.51529 0.10828 56808.941978 0.000683 0.34353 0.02899 0.98729 0 7.61203 0.32414 4.88468 0.20793 2.61495 0.19054 1.67953 0.12233 56808.943321 0.000660 0.37036 0.03138 0.97807 0 7.40987 0.32626 4.75905 0.20948 2.74435 0.19865 1.76415 0.12764 56808.944623 0.000642 0.38050 0.03172 0.96847 0 7.58765 0.33146 4.88736 0.21342 2.88707 0.20501 1.86324 0.13228 56808.946229 0.000964 0.34004 0.02411 0.98198 0 7.59077 0.27136 4.91073 0.17546 2.58117 0.15804 1.66868 0.10212
