/* ** ** 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 59070.918326 0.000417 0.25636 0.04066 0.96528 0 3.30075 0.23711 2.81016 0.20186 0.84619 0.11967 0.72062 0.10191 59070.919116 0.000373 0.26885 0.04284 0.96124 0 3.55053 0.26064 3.00107 0.22028 0.95457 0.13500 0.80779 0.11424 59070.919848 0.000359 0.25906 0.04140 0.96774 0 3.78642 0.27534 3.20399 0.23293 0.98091 0.13958 0.83025 0.11813 59070.920876 0.000668 0.29785 0.03711 0.98560 0 2.96515 0.17910 2.51721 0.15205 0.88316 0.09625 0.74966 0.08170 59070.985376 0.000315 0.32805 0.05447 0.98165 0 3.31176 0.27486 2.81018 0.23322 1.08641 0.15623 0.92241 0.13263 59070.986131 0.000440 0.22816 0.03629 0.96711 0 3.47016 0.23532 2.97229 0.20155 0.79177 0.11392 0.67838 0.09761 59070.986938 0.000367 0.24399 0.03881 0.97638 0 3.88677 0.27706 3.28751 0.23434 0.94831 0.13486 0.80385 0.11431 59070.987711 0.000405 0.24041 0.03819 0.98571 0 3.52181 0.24949 3.00168 0.21264 0.84669 0.12040 0.72230 0.10271 59070.988466 0.000350 0.29395 0.04845 0.97521 0 3.30073 0.26113 2.83132 0.22399 0.97026 0.14028 0.83227 0.12033 59070.989181 0.000365 0.27410 0.04523 0.99206 0 3.32188 0.25402 2.83906 0.21709 0.91053 0.13314 0.77783 0.11373 59070.989852 0.000307 0.34922 0.05909 0.97170 0 3.18530 0.27537 2.71047 0.23432 1.11238 0.16178 0.94873 0.13794 59070.990902 0.000744 0.22400 0.02717 0.96498 0 3.70489 0.19934 3.15268 0.16964 0.82991 0.09022 0.70727 0.07689
