/* ** ** 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 59345.167711 0.000755 0.25205 0.02036 0.98467 0 6.85036 0.25062 6.12858 0.22424 1.72662 0.12438 1.54576 0.11132 59345.169149 0.000683 0.27292 0.02199 0.98729 0 6.95209 0.25943 6.24430 0.23300 1.89733 0.13552 1.70596 0.12185 59345.170564 0.000732 0.25952 0.02094 0.99209 0 6.85988 0.25429 6.08595 0.22561 1.78025 0.12757 1.57940 0.11319 59345.171988 0.000692 0.26287 0.02120 0.97908 0 7.24012 0.26766 6.44025 0.23807 1.90324 0.13639 1.69415 0.12141 59345.173406 0.000726 0.26912 0.02183 0.98406 0 6.63023 0.24874 5.94917 0.22316 1.78430 0.12831 1.60069 0.11510 59345.174855 0.000723 0.26656 0.02154 0.98000 0 6.75444 0.24888 6.05857 0.22324 1.80049 0.12948 1.61376 0.11604 59345.176293 0.000715 0.26252 0.02106 0.97166 0 6.97614 0.25464 6.31248 0.23039 1.83141 0.13081 1.65621 0.11829 59345.177731 0.000723 0.26696 0.02154 0.98000 0 6.76067 0.24907 6.07928 0.22396 1.80482 0.12956 1.62579 0.11670
