/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 56379.943765 0.000307 0.40050 0.06756 0.97170 0 2.88293 0.26063 2.44026 0.22060 1.15462 0.16443 0.97715 0.13916 56379.944404 0.000333 0.38576 0.06234 0.94783 0 3.03322 0.25728 2.54883 0.21616 1.17010 0.16094 0.98316 0.13522 56379.945796 0.001059 0.44858 0.03851 0.96995 0 2.95896 0.14042 2.48863 0.11810 1.32733 0.09495 1.11719 0.07991 56379.947162 0.000307 0.37826 0.06284 0.96226 0 3.07334 0.26791 2.59614 0.22631 1.16252 0.16441 0.98203 0.13888 56379.947798 0.000330 0.36191 0.05955 0.99123 0 2.94303 0.25050 2.48599 0.21160 1.06511 0.14998 0.89966 0.12669 56379.948499 0.000370 0.33193 0.05455 0.95312 0 2.89848 0.23454 2.44829 0.19811 0.96210 0.13763 0.81271 0.11626 56379.949260 0.000391 0.29896 0.04827 0.98519 0 2.98305 0.23242 2.51913 0.19628 0.89182 0.12612 0.75313 0.10651 56379.949989 0.000339 0.37224 0.06180 0.99145 0 2.76517 0.24042 2.32107 0.20180 1.02931 0.14557 0.86351 0.12212 56379.950906 0.000579 0.46446 0.05764 0.97500 0 2.52561 0.17578 2.12507 0.14790 1.17305 0.12053 0.98611 0.10132 56379.951783 0.000298 0.38495 0.06451 0.99029 0 3.03158 0.27254 2.55498 0.22970 1.16700 0.16504 0.98203 0.13888 56379.952457 0.000376 0.27188 0.04419 0.98462 0 3.39001 0.25594 2.82965 0.21362 0.92169 0.13265 0.77065 0.11088 56379.953172 0.000339 0.41107 0.06996 0.99145 0 2.49900 0.23044 2.08135 0.19193 1.02727 0.14696 0.85475 0.12228 56379.953857 0.000347 0.37390 0.06276 0.98333 0 2.68272 0.23913 2.26257 0.20168 1.00306 0.14267 0.84457 0.12013 56379.954526 0.000321 0.42289 0.07206 0.98198 0 2.56023 0.24021 2.16207 0.20285 1.08269 0.15400 0.91430 0.13004
