/* ** ** 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 55370.578345 0.000558 0.54518 0.04811 0.97409 0 4.41707 0.23015 3.88972 0.20267 2.40810 0.17153 2.11838 0.15088 55370.579528 0.000625 0.45675 0.03941 0.99537 0 4.65810 0.22574 4.04936 0.19624 2.12757 0.15191 1.84862 0.13199 55370.580717 0.000564 0.45214 0.03875 0.98974 0 5.21816 0.25142 4.57528 0.22041 2.35933 0.16724 2.07183 0.14685 55370.581788 0.000506 0.57531 0.05202 0.99429 0 4.57869 0.25297 3.96856 0.21925 2.63418 0.18855 2.27959 0.16315 55370.582963 0.000668 0.41743 0.03547 0.98268 0 4.83091 0.22251 4.19635 0.19326 2.01655 0.14398 1.75089 0.12501 55370.584299 0.000668 0.43689 0.03732 0.98701 0 4.65408 0.22066 4.00827 0.19005 2.03331 0.14448 1.75026 0.12436 55370.585526 0.000558 0.50385 0.04461 0.98964 0 4.66035 0.23954 4.09818 0.21065 2.34810 0.16931 2.06408 0.14881 55370.586643 0.000558 0.54096 0.04802 0.98446 0 4.45464 0.23391 3.87085 0.20324 2.40976 0.17248 2.09394 0.14984 55370.587789 0.000587 0.47941 0.04172 0.98522 0 4.72876 0.23394 4.14407 0.20501 2.26703 0.16227 1.98325 0.14194 55370.588990 0.000613 0.44998 0.03890 0.99528 0 4.78868 0.23085 4.16762 0.20090 2.15482 0.15462 1.87605 0.13460 55370.590283 0.000680 0.51118 0.04193 0.98723 0 4.37299 0.20911 3.82524 0.18289 2.23538 0.14900 1.95840 0.13052
