/* ** ** 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 53561.785355 0.000341 0.34217 0.05419 0.94068 0 3.48957 0.27691 2.86676 0.22744 1.19403 0.16363 0.97882 0.13409 53561.786811 0.001114 0.40037 0.03390 0.96883 0 3.15041 0.14223 2.65219 0.11974 1.26134 0.09036 1.06183 0.07607 53561.790046 0.002121 0.40784 0.02474 0.97109 0 3.18642 0.10402 2.68071 0.08751 1.29955 0.06643 1.09314 0.05588 53561.793735 0.000029 0.16861 0.11728 0.99303 0 3.88785 1.07829 3.28405 0.91083 0.65552 0.41814 0.55372 0.35320 53561.852697 0.001019 0.43654 0.03752 0.97443 0 3.16827 0.15042 2.64012 0.12534 1.38309 0.09909 1.15467 0.08272 53561.854810 0.001094 0.37269 0.03143 0.96032 0 3.54920 0.15470 2.91943 0.12725 1.32274 0.09549 1.08668 0.07845 53561.856248 0.000344 0.32780 0.05382 0.93277 0 3.32622 0.26793 2.73648 0.22042 1.09033 0.15600 0.89316 0.12779 53561.856902 0.000310 0.30056 0.04944 0.97196 0 3.82350 0.30463 3.16296 0.25198 1.14921 0.16538 0.94835 0.13648 53561.857515 0.000304 0.28676 0.04667 0.96190 0 4.12362 0.31330 3.39873 0.25819 1.18249 0.17021 0.97651 0.14053 53561.858895 0.001076 0.41058 0.03500 0.96505 0 3.25801 0.14890 2.67539 0.12226 1.33767 0.09625 1.09892 0.07907 53561.860319 0.000347 0.37762 0.05864 0.97500 0 3.19975 0.26199 2.61851 0.21440 1.20829 0.15945 0.98872 0.13047 53561.861132 0.000466 0.33406 0.04638 0.95031 0 3.36087 0.23014 2.76179 0.18911 1.12272 0.13559 0.92263 0.11141
