/* ** ** 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 55603.786324 0.000926 0.42802 0.03639 0.97812 0 3.48447 0.16134 2.97671 0.13782 1.49141 0.10634 1.27426 0.09086 55603.788118 0.000868 0.51229 0.04490 0.98333 0 3.08198 0.15723 2.63270 0.13430 1.57887 0.11252 1.34893 0.09613 55603.789949 0.000964 0.42158 0.03590 0.98498 0 3.39775 0.15730 2.86632 0.13270 1.43243 0.10240 1.20988 0.08649 55603.791775 0.000862 0.50883 0.04444 0.97315 0 3.19516 0.16188 2.70124 0.13685 1.62579 0.11567 1.37407 0.09777 55603.793517 0.000880 0.48769 0.04221 0.97697 0 3.26428 0.16185 2.75809 0.13674 1.59197 0.11293 1.34537 0.09543 55603.795447 0.001050 0.51232 0.03938 0.98072 0 3.32746 0.14872 2.83224 0.12657 1.70473 0.10661 1.45236 0.09083
