/* ** ** 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 60054.702891 0.000523 0.57079 0.15606 0.97222 1 0.89710 0.14608 0.42079 0.06851 0.51205 0.11246 0.23853 0.05239 60054.703937 0.000523 0.40947 0.11032 1.00000 1 1.11895 0.16549 0.53966 0.07981 0.45818 0.10318 0.22079 0.04971 60054.704808 0.000349 0.54860 0.15536 0.95833 1 1.31596 0.22602 0.62699 0.10767 0.72193 0.16256 0.34559 0.07781 60054.705505 0.000349 0.62288 0.17317 0.95833 1 1.21544 0.20933 0.58907 0.10143 0.75708 0.16522 0.36522 0.07970 60054.706449 0.000596 0.44035 0.11990 0.97561 1 0.94119 0.14620 0.45127 0.07009 0.41446 0.09269 0.20000 0.04472 60054.707510 0.000465 0.43031 0.11455 0.93750 1 1.28917 0.18611 0.61936 0.08940 0.55475 0.12407 0.26667 0.05963 60054.708410 0.000436 0.63444 0.17935 1.00000 1 0.93574 0.16810 0.44286 0.07954 0.59367 0.12958 0.28000 0.06110 60054.709296 0.000450 0.62197 0.17841 1.00000 1 0.86183 0.15481 0.41334 0.07424 0.53604 0.11988 0.25807 0.05771 60054.710226 0.000479 0.44287 0.12125 1.00000 1 1.12805 0.17317 0.53428 0.08200 0.49958 0.11326 0.23930 0.05425 60054.711185 0.000479 0.30125 0.07556 1.00000 1 1.75596 0.21706 0.84829 0.10485 0.52898 0.11544 0.25455 0.05555 60054.712303 0.000639 0.30402 0.07601 1.00000 1 1.32104 0.16119 0.62896 0.07674 0.40162 0.08765 0.19091 0.04166 60054.713320 0.000378 0.74952 0.22210 0.96154 1 0.88150 0.17139 0.42788 0.08319 0.66070 0.14774 0.32000 0.07155 60054.714482 0.000784 0.48553 0.09940 0.96521 1 1.19550 0.14102 0.56851 0.06704 0.58045 0.09713 0.27529 0.04606
