/* ** ** 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 56757.585799 0.000304 0.50799 0.08985 0.97143 0 2.35593 0.24209 1.90350 0.19562 1.19680 0.17229 0.96681 0.13916 56757.586456 0.000353 0.57815 0.10406 1.00000 0 1.74289 0.19217 1.41295 0.15579 1.00766 0.14335 0.81680 0.11619 56757.587119 0.000310 0.42836 0.07215 0.99065 0 2.75190 0.25762 2.25051 0.21068 1.17882 0.16507 0.96387 0.13497 56757.587775 0.000347 0.36678 0.06142 0.97500 0 2.85146 0.25195 2.32008 0.20499 1.04587 0.14878 0.85170 0.12116 56757.588470 0.000347 0.48458 0.08498 0.98333 0 2.11475 0.21443 1.73421 0.17584 1.02477 0.14663 0.84010 0.12021 56757.589124 0.000307 0.52723 0.09264 0.96226 0 2.26310 0.23346 1.85293 0.19115 1.19318 0.16973 0.97695 0.13897 56757.589963 0.000532 0.51857 0.06774 0.97283 0 2.36710 0.18068 1.92506 0.14692 1.22750 0.13012 0.99607 0.10558 56757.590802 0.000307 0.57327 0.10260 0.97170 0 2.07065 0.22712 1.69699 0.18614 1.18705 0.16787 0.97249 0.13753 56757.591441 0.000333 0.51188 0.08940 0.97391 0 2.13318 0.21613 1.73283 0.17556 1.09193 0.15533 0.88973 0.12656 56757.592104 0.000330 0.40213 0.06820 1.00000 0 2.65736 0.24541 2.17288 0.20066 1.06859 0.15200 0.87412 0.12434 56757.592770 0.000336 0.41975 0.07124 0.95690 0 2.62567 0.23960 2.13880 0.19516 1.10213 0.15771 0.89308 0.12779 56757.593510 0.000399 0.33217 0.05485 0.97826 0 2.70318 0.22272 2.20858 0.18193 0.89791 0.12848 0.73431 0.10507 56757.594228 0.000318 0.46676 0.08003 1.00000 0 2.41782 0.23649 1.97459 0.19313 1.12855 0.15894 0.92411 0.13015 56757.594859 0.000312 0.49659 0.08750 0.96296 0 2.34902 0.24152 1.91857 0.19727 1.16650 0.16692 0.95319 0.13639 56757.595550 0.000379 0.41864 0.07163 0.96183 0 2.29348 0.21218 1.86793 0.17281 0.96014 0.13820 0.78265 0.11265 56757.596575 0.000645 0.40826 0.05186 0.96413 0 2.49086 0.17025 2.02096 0.13813 1.01693 0.10889 0.82207 0.08800
