/* ** ** 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 58191.384953 0.000506 0.38252 0.06446 0.98286 0 1.81516 0.16391 1.51464 0.13677 0.69433 0.09878 0.57929 0.08242 58191.385804 0.000344 0.52982 0.09445 0.97479 0 1.95968 0.20759 1.62303 0.17191 1.03828 0.14886 0.86253 0.12367 58191.386510 0.000362 0.52978 0.09508 0.96800 0 1.83212 0.19406 1.52914 0.16196 0.97062 0.14062 0.81033 0.11740 58191.387317 0.000446 0.42981 0.07373 0.98701 0 1.82851 0.17525 1.52516 0.14618 0.78591 0.11181 0.65551 0.09326 58191.388147 0.000385 0.47335 0.08261 0.97744 0 1.92786 0.19251 1.61029 0.16080 0.91256 0.13061 0.76237 0.10912 58191.388963 0.000431 0.40982 0.06974 0.99329 0 1.97267 0.18418 1.63637 0.15280 0.80845 0.11503 0.67323 0.09578 58191.389863 0.000469 0.37202 0.06266 0.96914 0 2.03350 0.18056 1.69106 0.15014 0.75650 0.10828 0.63126 0.09035 58191.390717 0.000385 0.45195 0.08006 0.99248 0 1.94826 0.19359 1.62594 0.16156 0.88051 0.12914 0.73479 0.10776 58191.391527 0.000425 0.47390 0.08139 0.93878 0 1.85962 0.18275 1.55468 0.15278 0.88128 0.12413 0.73653 0.10374 58191.392302 0.000350 0.52151 0.09159 0.96694 0 1.98306 0.20578 1.65756 0.17200 1.03419 0.14653 0.86420 0.12245 58191.393095 0.000443 0.35041 0.05836 0.99346 0 2.24144 0.19404 1.87091 0.16196 0.78542 0.11174 0.65551 0.09326 58191.393984 0.000446 0.41470 0.07115 0.94805 0 1.93793 0.17807 1.61901 0.14876 0.80366 0.11643 0.67158 0.09730 58191.395132 0.000703 0.48495 0.06141 0.97942 0 1.96844 0.14524 1.64458 0.12134 0.95460 0.09825 0.79743 0.08207
