/* ** ** 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 58145.489212 0.000434 0.38983 0.06588 0.98667 0 2.06126 0.18520 1.71924 0.15448 0.80353 0.11501 0.66966 0.09585 58145.490164 0.000518 0.31466 0.05212 0.98324 0 2.13107 0.17448 1.77946 0.14565 0.67056 0.09656 0.56012 0.08065 58145.491003 0.000321 0.52509 0.09400 0.97297 0 2.09791 0.22058 1.73031 0.18193 1.10160 0.15961 0.90790 0.13153 58145.491764 0.000440 0.39606 0.06720 0.96711 0 2.05202 0.18703 1.69768 0.15473 0.81272 0.11632 0.67422 0.09650 58145.492650 0.000446 0.35690 0.05911 0.98052 0 2.22654 0.19187 1.86292 0.16052 0.79466 0.11239 0.66336 0.09381 58145.493555 0.000460 0.37573 0.06277 0.98742 0 2.05230 0.18250 1.69252 0.15051 0.77111 0.10906 0.63800 0.09023 58145.494417 0.000402 0.38170 0.06457 1.00000 0 2.24496 0.20240 1.86402 0.16805 0.85689 0.12264 0.71302 0.10205 58145.495196 0.000376 0.46928 0.08126 0.99231 0 2.00766 0.20061 1.65656 0.16555 0.94215 0.13325 0.77649 0.10981 58145.496067 0.000495 0.39465 0.06609 0.96491 0 1.85488 0.16630 1.53489 0.13759 0.73203 0.10353 0.60707 0.08585 58145.497056 0.000495 0.28303 0.04630 0.99415 0 2.45994 0.19077 2.05057 0.15903 0.69623 0.10027 0.57989 0.08350 58145.498063 0.000512 0.35558 0.05934 0.98870 0 1.93370 0.16863 1.60147 0.13964 0.68758 0.09784 0.56936 0.08100 58145.498937 0.000362 0.44878 0.07607 0.96800 0 2.26217 0.21607 1.88356 0.17990 1.01522 0.14217 0.84438 0.11824
