/* ** ** 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 57930.213161 0.000886 0.21045 0.05181 0.98361 1 2.52028 0.25934 0.63513 0.06536 0.53040 0.11861 0.13333 0.02981 57930.215035 0.000988 0.19992 0.05000 0.97059 1 2.34659 0.23615 0.59353 0.05973 0.46913 0.10742 0.11856 0.02715 57930.216851 0.000828 0.20508 0.05091 0.98246 1 2.74501 0.28541 0.69505 0.07226 0.56294 0.12689 0.14181 0.03196 57930.218114 0.000436 0.57252 0.16422 1.00000 1 1.82210 0.32331 0.46308 0.08217 1.04320 0.23511 0.26472 0.05966 57930.219276 0.000726 0.30743 0.07693 0.96000 1 2.26267 0.27708 0.56897 0.06967 0.69561 0.15180 0.17500 0.03819 57930.220743 0.000741 0.24372 0.06166 1.00000 1 2.53560 0.29135 0.63680 0.07317 0.61797 0.13930 0.15572 0.03509 57930.222167 0.000683 0.37308 0.09638 0.97872 1 1.93526 0.26246 0.48629 0.06595 0.72201 0.15876 0.18134 0.03987
