/* ** ** 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 58227.261869 0.000593 0.40243 0.06871 0.98049 0 1.46851 0.13559 1.23535 0.11406 0.59097 0.08488 0.49719 0.07139 58227.262983 0.000521 0.42768 0.07382 0.97778 0 1.57109 0.14914 1.30987 0.12434 0.67192 0.09687 0.55961 0.08067 58227.263961 0.000457 0.36447 0.06113 0.98101 0 2.11858 0.18793 1.75859 0.15599 0.77215 0.10990 0.64263 0.09146 58227.264939 0.000521 0.37279 0.06264 0.96667 0 1.83184 0.16077 1.52399 0.13374 0.68289 0.09785 0.56925 0.08154 58227.265874 0.000414 0.45307 0.07765 1.00000 0 1.86522 0.18434 1.57711 0.15587 0.84507 0.11833 0.71448 0.10005 58227.266843 0.000556 0.38884 0.06542 0.95833 0 1.65815 0.14877 1.39052 0.12476 0.64475 0.09176 0.54135 0.07705 58227.267708 0.000310 0.26311 0.06680 0.99065 0 1.71295 0.20587 1.44335 0.17345 0.45069 0.10078 0.37799 0.08452 58227.268336 0.000318 0.25307 0.06648 0.97273 0 1.67686 0.19781 1.41785 0.16725 0.42436 0.09961 0.35879 0.08422 58227.269010 0.000356 0.25082 0.05745 0.98374 0 1.88550 0.19591 1.58677 0.16488 0.47293 0.09654 0.39736 0.08111 58227.269890 0.000524 0.43707 0.07557 0.96133 0 1.54507 0.14964 1.30035 0.12594 0.67530 0.09673 0.56925 0.08154 58227.271015 0.000602 0.29686 0.04824 0.97596 0 1.97055 0.15456 1.65323 0.12965 0.58498 0.08326 0.49068 0.06984 58227.272257 0.000639 0.43961 0.06265 0.97285 0 1.82094 0.14450 1.52487 0.12099 0.80051 0.09476 0.66829 0.07911
