/* ** ** 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 58200.359637 0.000373 0.48317 0.08392 0.99225 0 1.87093 0.18861 1.62199 0.16351 0.90398 0.12785 0.78255 0.11067 58200.360456 0.000446 0.42145 0.07180 0.95455 0 1.86949 0.17754 1.61948 0.15381 0.78790 0.11143 0.68141 0.09637 58200.361347 0.000446 0.40219 0.06804 0.98052 0 1.94989 0.18105 1.64838 0.15305 0.78423 0.11091 0.66336 0.09381 58200.362323 0.000530 0.31315 0.05117 0.97268 0 2.05851 0.16536 1.78323 0.14324 0.64462 0.09172 0.55973 0.07964 58200.363338 0.000486 0.35901 0.06015 0.97619 0 1.95578 0.17010 1.68858 0.14686 0.70214 0.10054 0.60424 0.08650 58200.364305 0.000480 0.36846 0.06106 0.95181 0 2.03325 0.17460 1.73531 0.14902 0.74918 0.10619 0.63987 0.09068 58200.365228 0.000443 0.46037 0.07964 0.98039 0 1.72686 0.17131 1.46529 0.14535 0.79499 0.11267 0.67399 0.09551 58200.366107 0.000437 0.40353 0.06867 0.98013 0 1.93880 0.17846 1.66478 0.15324 0.78236 0.11199 0.66956 0.09585 58200.366999 0.000454 0.40413 0.06940 0.98726 0 1.85920 0.17384 1.57554 0.14731 0.75136 0.10823 0.63587 0.09159 58200.367794 0.000341 0.57527 0.10324 0.96610 0 1.78588 0.19528 1.52172 0.16638 1.02736 0.14619 0.87396 0.12435 58200.368790 0.000654 0.36090 0.05073 0.96018 0 2.12473 0.15479 1.79672 0.13088 0.76682 0.09219 0.64806 0.07791
