/* ** ** 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 59265.496719 0.000524 0.20773 0.03233 0.97790 0 3.27683 0.21288 2.72589 0.17710 0.68071 0.09627 0.56591 0.08003 59265.497607 0.000365 0.29831 0.04884 0.99206 0 3.15931 0.25117 2.65792 0.21131 0.94245 0.13489 0.79289 0.11348 59265.498521 0.000550 0.17203 0.02636 0.98421 0 3.72297 0.21935 3.12141 0.18391 0.64046 0.09058 0.53565 0.07575 59265.499496 0.000425 0.24680 0.03907 0.98639 0 3.33957 0.23765 2.79775 0.19908 0.82419 0.11656 0.69081 0.09769 59265.500344 0.000422 0.22253 0.03495 0.98630 0 3.71504 0.25380 3.12597 0.21356 0.82670 0.11691 0.69560 0.09837 59265.501227 0.000460 0.22980 0.03611 0.96855 0 3.36342 0.23054 2.83046 0.19401 0.77290 0.10930 0.65043 0.09199 59265.502150 0.000463 0.22663 0.03590 0.96875 0 3.35312 0.22762 2.82144 0.19153 0.75992 0.10876 0.63943 0.09152 59265.503162 0.000544 0.19723 0.03087 0.96277 0 3.29955 0.20917 2.77632 0.17600 0.65077 0.09314 0.54758 0.07837 59265.504632 0.000926 0.21464 0.02390 0.98750 0 3.46634 0.16410 2.91632 0.13806 0.74402 0.07500 0.62596 0.06310
