/* ** ** 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 56487.244017 0.000793 0.34642 0.02867 0.98175 0 6.96873 0.29170 4.31891 0.18021 2.41413 0.17238 1.48997 0.10609 56487.245620 0.000810 0.32562 0.02693 0.97143 0 6.79635 0.27636 4.45703 0.18120 2.21303 0.15938 1.45169 0.10452 56487.247229 0.000799 0.32134 0.02651 0.98913 0 6.91216 0.28299 4.53072 0.18545 2.22115 0.15905 1.45726 0.10434 56487.248780 0.000752 0.36310 0.03088 0.97308 0 6.31905 0.27441 4.24317 0.18425 2.29443 0.16775 1.54159 0.11270 56487.250357 0.000825 0.31349 0.02616 0.96842 0 6.73086 0.27041 4.50421 0.18092 2.11009 0.15431 1.41312 0.10331 56487.252001 0.000819 0.32093 0.02682 0.95053 0 6.82800 0.27592 4.51940 0.18259 2.19133 0.16028 1.44990 0.10600 56487.254194 0.001374 0.30286 0.01959 0.96803 0 6.86090 0.21293 4.58763 0.14235 2.07790 0.11790 1.39071 0.07888 56487.310754 0.000865 0.33045 0.02736 0.98328 0 5.63993 0.23340 4.07861 0.16860 1.86370 0.13364 1.34863 0.09663 56487.312461 0.000842 0.31871 0.02625 0.97594 0 6.23629 0.25230 4.39416 0.17776 1.98758 0.14256 1.39950 0.10034 56487.314223 0.000920 0.28034 0.02297 0.97170 0 6.44269 0.24418 4.53275 0.17175 1.80615 0.13117 1.26967 0.09218 56487.315907 0.000764 0.36403 0.03055 0.98485 0 5.99036 0.25938 4.18470 0.18116 2.18069 0.15677 1.52098 0.10934 56487.317583 0.000911 0.29664 0.02417 0.98413 0 6.20760 0.24327 4.32171 0.16936 1.84144 0.13155 1.28239 0.09158 56487.319455 0.000961 0.28856 0.02349 0.97892 0 5.99142 0.23171 4.21991 0.16314 1.72888 0.12387 1.21999 0.08741 56487.321310 0.000894 0.33878 0.02743 0.98382 0 5.78452 0.23594 4.05542 0.16535 1.95966 0.13708 1.37333 0.09603
