/* ** ** 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 58297.669331 0.000509 0.13210 0.03189 0.98295 0 2.03379 0.16653 1.72939 0.14158 0.26865 0.06101 0.22854 0.05188 58297.670445 0.000605 0.13622 0.03180 0.98086 0 1.75943 0.14597 1.50385 0.12478 0.23966 0.05230 0.20522 0.04478 58297.671411 0.000362 0.18099 0.04417 0.96800 0 2.13439 0.20860 1.82708 0.17857 0.38631 0.08638 0.33113 0.07404 58297.672170 0.000396 0.17830 0.04520 0.97810 0 1.86776 0.18174 1.61082 0.15674 0.33302 0.07795 0.28714 0.06721 58297.672985 0.000420 0.16810 0.04133 0.98621 0 1.90901 0.18043 1.64564 0.15554 0.32090 0.07284 0.27648 0.06276 58297.673859 0.000454 0.14648 0.03511 0.98726 0 2.04650 0.17678 1.76498 0.15246 0.29977 0.06703 0.25849 0.05780 58297.674878 0.000564 0.12590 0.02987 0.94872 0 1.99642 0.15829 1.72089 0.13644 0.25135 0.05620 0.21658 0.04843 58297.675885 0.000443 0.16519 0.04112 0.96078 0 1.86374 0.17531 1.60655 0.15111 0.30787 0.07096 0.26535 0.06116 58297.676770 0.000443 0.15636 0.03771 0.97386 0 1.99459 0.18032 1.71896 0.15541 0.31188 0.06974 0.26890 0.06013 58297.677537 0.000324 0.25227 0.06191 0.94643 0 1.82628 0.20509 1.57329 0.17668 0.46071 0.10053 0.39689 0.08661 58297.678865 0.001004 0.15252 0.02667 0.97695 0 1.72931 0.11104 1.49057 0.09571 0.26376 0.04289 0.22734 0.03697
