/* ** ** 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 55214.590911 0.000561 0.51797 0.06667 0.97423 0 3.34702 0.25314 1.89684 0.14295 1.73367 0.18057 0.99089 0.10284 55214.591848 0.000376 0.43871 0.07363 0.98462 0 3.63008 0.33898 1.84381 0.17218 1.59256 0.22210 0.80981 0.11293 55214.592531 0.000307 0.47180 0.08161 0.96226 0 4.06324 0.39987 2.06730 0.20344 1.91704 0.27270 0.97695 0.13897 55214.593211 0.000373 0.39282 0.06825 0.99225 0 3.78935 0.35364 1.93232 0.18033 1.48854 0.21816 0.75829 0.11111 55214.593883 0.000298 0.56713 0.10152 0.98058 0 3.43506 0.37327 1.73960 0.18904 1.94813 0.27711 0.98663 0.14035 55214.594528 0.000347 0.50282 0.08817 0.97500 0 3.34762 0.34318 1.69342 0.17361 1.68326 0.23947 0.85170 0.12116 55214.595188 0.000312 0.48550 0.08388 0.93519 0 4.05904 0.39789 2.03624 0.19957 1.97066 0.28035 0.98663 0.14035 55214.595813 0.000312 0.50246 0.08878 0.95370 0 3.73507 0.37820 1.89745 0.19213 1.87673 0.27177 0.95240 0.13790 55214.596507 0.000382 0.50754 0.08042 0.91667 0 3.83230 0.34866 1.95089 0.17749 1.94504 0.25234 0.98911 0.12832 55214.597239 0.000350 0.39065 0.06626 0.99174 0 4.15640 0.37859 2.11473 0.19262 1.62369 0.23232 0.82610 0.11821 55214.598000 0.000405 0.39617 0.06713 0.96429 0 3.64579 0.33091 1.85284 0.16817 1.44437 0.20668 0.73431 0.10507 55214.598709 0.000304 0.62179 0.11408 0.98095 0 3.05958 0.35129 1.54522 0.17742 1.90243 0.27223 0.96244 0.13771 55214.599322 0.000310 0.49949 0.08815 0.94393 0 3.87316 0.39570 1.95722 0.19993 1.93459 0.27842 0.97638 0.14054 55214.599999 0.000367 0.40203 0.06917 0.95276 0 3.97935 0.36973 2.01480 0.18721 1.59982 0.23165 0.81072 0.11738 55214.601001 0.000634 0.49480 0.05995 0.97260 0 3.95754 0.27920 1.98769 0.14022 1.95820 0.19288 0.98482 0.09699 55214.602213 0.000579 0.45819 0.06044 0.93448 0 3.91661 0.28462 1.97288 0.14337 1.79455 0.19754 0.90522 0.09964 55214.653144 0.000987 0.45736 0.03968 0.97654 0 3.52148 0.17154 2.59729 0.12607 1.61058 0.11561 1.19077 0.08519 55214.655103 0.000972 0.46552 0.04012 0.97321 0 3.42187 0.16652 2.61674 0.12734 1.59295 0.11330 1.21895 0.08670 55214.656952 0.000877 0.47869 0.04139 0.96700 0 3.68084 0.17992 2.83889 0.13876 1.76200 0.12569 1.35687 0.09679 55214.658796 0.000966 0.40387 0.03414 0.97305 0 3.90928 0.17724 3.02559 0.13716 1.57886 0.11264 1.22327 0.08726 55214.660072 0.000310 0.36276 0.06006 0.96262 0 3.48933 0.29910 2.70467 0.23184 1.26580 0.17930 0.98189 0.13908 55214.661426 0.001045 0.46189 0.04002 0.97507 0 3.16155 0.15506 2.44103 0.11972 1.46029 0.10432 1.12797 0.08058 55214.663526 0.001056 0.45941 0.03846 0.97808 0 3.36158 0.15777 2.58910 0.12151 1.54435 0.10706 1.18910 0.08244
