/* ** ** 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 59540.889884 0.000301 0.18766 0.03004 0.97115 0 5.67987 0.35696 5.11882 0.32170 1.06588 0.15692 0.96053 0.14141 59540.891181 0.000995 0.26136 0.02108 0.97384 0 5.03836 0.18662 4.52465 0.16758 1.31683 0.09436 1.18347 0.08480 59540.893134 0.000958 0.23939 0.01911 0.97885 0 5.67006 0.19932 5.11150 0.17969 1.35734 0.09726 1.22365 0.08768 59540.894384 0.000292 0.21865 0.03430 1.00000 0 5.06511 0.34355 4.53844 0.30787 1.10748 0.15663 0.99175 0.14025 59540.895752 0.001076 0.21655 0.01712 0.97312 0 5.61116 0.18742 5.05769 0.16893 1.21507 0.08707 1.09520 0.07848 59540.897839 0.001010 0.23987 0.01935 0.99140 0 5.26515 0.18775 4.73799 0.16896 1.26293 0.09141 1.13674 0.08228 59540.899268 0.000420 0.21277 0.02854 0.97241 0 5.10882 0.28657 4.60425 0.25826 1.08702 0.13242 0.97966 0.11934 59540.899997 0.000310 0.19302 0.03037 0.98131 0 5.52915 0.34900 4.98434 0.31461 1.06724 0.15382 0.96210 0.13867 59540.900631 0.000324 0.21599 0.03229 0.99107 0 5.09929 0.32915 4.59569 0.29665 1.10141 0.14851 0.99264 0.13385 59540.901864 0.000909 0.21053 0.01866 0.98726 0 5.35946 0.20105 4.83242 0.18128 1.12831 0.09061 1.01735 0.08170
