/* ** ** 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 55212.850534 0.000518 0.31303 0.03891 0.95531 0 3.94614 0.23692 3.16958 0.19029 1.23525 0.13444 0.99277 0.10805 55212.851938 0.000885 0.38435 0.03222 0.98366 0 4.26084 0.18826 3.44164 0.15206 1.63765 0.11665 1.32248 0.09420 55212.853723 0.000900 0.45467 0.03929 0.98392 0 3.52686 0.17031 2.84647 0.13746 1.60356 0.11490 1.29407 0.09273 55212.855508 0.000885 0.44067 0.03766 0.97059 0 3.76297 0.17712 3.03688 0.14295 1.65822 0.11829 1.33854 0.09549 55212.857366 0.000972 0.42402 0.03615 0.96131 0 3.58250 0.16554 2.89117 0.13359 1.51904 0.10885 1.22596 0.08785 55212.859206 0.000868 0.46729 0.04046 0.97667 0 3.60977 0.17817 2.91114 0.14369 1.68681 0.11998 1.36036 0.09676 55212.860939 0.000865 0.46377 0.04016 0.98662 0 3.59437 0.17531 2.89842 0.14137 1.66695 0.11927 1.34408 0.09617 55212.862855 0.001050 0.45982 0.03620 0.97709 0 3.62869 0.16059 2.92594 0.12949 1.66856 0.10863 1.34531 0.08759 55212.917396 0.000747 0.51419 0.04525 0.98450 0 3.69091 0.18936 3.05178 0.15655 1.89784 0.13570 1.57068 0.11230 55212.919007 0.000865 0.41473 0.03525 0.98328 0 3.98516 0.18314 3.26288 0.14992 1.65276 0.11815 1.35370 0.09675 55212.920683 0.000810 0.44618 0.03856 0.98214 0 3.89642 0.18640 3.21178 0.15364 1.73852 0.12514 1.43427 0.10323 55212.922260 0.000767 0.50477 0.04422 0.98868 0 3.62432 0.18483 3.00752 0.15337 1.82943 0.13032 1.51934 0.10823 55212.924013 0.000987 0.38789 0.03245 0.97067 0 3.77403 0.16607 3.11427 0.13703 1.46391 0.10417 1.20710 0.08589 55212.925847 0.000848 0.47391 0.04118 0.97611 0 3.57109 0.17528 2.92561 0.14360 1.69237 0.12133 1.38793 0.09949 55212.927448 0.000752 0.47793 0.04168 0.98077 0 4.00215 0.19957 3.25373 0.16224 1.91274 0.13686 1.55492 0.11125 55212.929363 0.001163 0.43764 0.03184 0.97512 0 3.89312 0.15551 3.20851 0.12815 1.70380 0.10362 1.40348 0.08534
