/* ** ** 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 59285.160359 0.000347 0.28800 0.04642 0.97500 0 3.54753 0.27248 2.99567 0.22996 1.02170 0.14476 0.86420 0.12245 59285.161204 0.000498 0.30210 0.03850 0.94767 0 3.86986 0.23578 3.27603 0.19957 1.16908 0.13087 0.98903 0.11071 59285.162142 0.000440 0.20753 0.03203 0.98684 0 3.85176 0.25022 3.28259 0.21325 0.79934 0.11193 0.68113 0.09538 59285.163091 0.000509 0.18354 0.02828 0.97727 0 3.72327 0.22791 3.17287 0.19422 0.68335 0.09664 0.58236 0.08236 59285.163910 0.000310 0.27656 0.04457 0.98131 0 4.02516 0.30477 3.43123 0.25980 1.11319 0.15838 0.94893 0.13501 59285.164523 0.000304 0.29725 0.04816 0.98095 0 3.83792 0.30339 3.27168 0.25863 1.14082 0.16134 0.97249 0.13753 59285.165249 0.000422 0.21582 0.03460 0.97945 0 3.73118 0.24930 3.16161 0.21123 0.80525 0.11736 0.68196 0.09941 59285.166213 0.000541 0.18893 0.02956 0.98930 0 3.32638 0.21035 2.83553 0.17931 0.62846 0.08995 0.53572 0.07668 59285.167240 0.000486 0.21729 0.03418 0.98810 0 3.24027 0.21749 2.76226 0.18541 0.70409 0.10017 0.60022 0.08540 59285.168125 0.000399 0.21861 0.03456 0.97101 0 3.96896 0.26655 3.38325 0.22721 0.86766 0.12419 0.73961 0.10586 59285.168872 0.000347 0.27903 0.04543 0.96667 0 3.57290 0.27158 3.04571 0.23151 0.99693 0.14356 0.84981 0.12237 59285.169673 0.000454 0.24749 0.03482 0.97452 0 3.91018 0.24475 3.33311 0.20863 0.96772 0.12192 0.82490 0.10393
