/* ** ** 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 58551.337743 0.000336 0.42532 0.07257 0.94828 0 2.53068 0.23516 2.12263 0.19725 1.07636 0.15404 0.90117 0.12895 58551.338440 0.000362 0.42512 0.07272 0.97600 0 2.25748 0.21159 1.91122 0.17913 0.95970 0.13733 0.81253 0.11627 58551.339225 0.000422 0.42679 0.07167 0.95205 0 2.02535 0.18526 1.71336 0.15672 0.86441 0.12174 0.73130 0.10299 58551.340096 0.000448 0.37249 0.06265 0.96774 0 2.09700 0.18539 1.77421 0.15685 0.78111 0.11177 0.66086 0.09456 58551.340938 0.000394 0.43989 0.07564 0.98529 0 1.99816 0.19298 1.69057 0.16328 0.87898 0.12504 0.74364 0.10579 58551.341727 0.000391 0.36395 0.06079 0.97037 0 2.45736 0.21175 2.07925 0.17917 0.89434 0.12797 0.75671 0.10828 58551.342564 0.000446 0.31588 0.05115 0.94805 0 2.60527 0.20825 2.20413 0.17619 0.82295 0.11590 0.69624 0.09806 58551.343412 0.000402 0.39638 0.06768 0.97842 0 2.17372 0.20249 1.83888 0.17130 0.86161 0.12329 0.72889 0.10430 58551.344259 0.000446 0.31866 0.05168 0.95455 0 2.56525 0.20628 2.17007 0.17450 0.81743 0.11512 0.69151 0.09739 58551.345055 0.000350 0.44744 0.07602 0.94215 0 2.32166 0.21859 1.96377 0.18489 1.03881 0.14691 0.87866 0.12426 58551.345822 0.000417 0.36314 0.06135 0.96528 0 2.31994 0.20121 1.96250 0.17021 0.84246 0.12215 0.71264 0.10333 58551.346560 0.000321 0.49356 0.08658 0.98198 0 2.18981 0.22479 1.85228 0.19014 1.08081 0.15375 0.91420 0.13005 58551.347726 0.000845 0.34795 0.04226 0.98288 0 2.19986 0.13795 1.86056 0.11667 0.76544 0.07962 0.64736 0.06734
