/* ** ** 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 58166.410552 0.000307 0.24526 0.06329 0.98113 0 1.81827 0.21162 1.52252 0.17719 0.44595 0.10271 0.37523 0.08644 58166.411409 0.000550 0.33227 0.05511 0.95789 0 1.94969 0.16343 1.63711 0.13722 0.64782 0.09271 0.54464 0.07794 58166.412448 0.000489 0.42132 0.07260 0.96450 0 1.70968 0.16191 1.42927 0.13535 0.72033 0.10370 0.60492 0.08708 58166.413423 0.000486 0.45975 0.08069 0.97024 0 1.56768 0.15742 1.31536 0.13209 0.72074 0.10375 0.60492 0.08708 58166.414511 0.000602 0.29015 0.04715 0.97115 0 2.02844 0.15934 1.70034 0.13357 0.58855 0.08373 0.49329 0.07017 58166.415428 0.000315 0.23154 0.05701 0.97248 0 2.01371 0.21740 1.69152 0.18261 0.46625 0.10319 0.39197 0.08675 58166.416195 0.000451 0.49384 0.08509 0.95513 0 1.64590 0.16336 1.38147 0.13712 0.81282 0.11448 0.68220 0.09608 58166.417132 0.000486 0.34508 0.05769 0.95833 0 2.11240 0.17951 1.77457 0.15080 0.72895 0.10494 0.61244 0.08816 58166.418243 0.000625 0.32124 0.05251 0.97222 0 1.76638 0.14475 1.48460 0.12166 0.56744 0.08025 0.47698 0.06746 58166.419488 0.000619 0.28290 0.04565 0.97196 0 2.01596 0.15352 1.69292 0.12892 0.57031 0.08113 0.47906 0.06815 58166.421160 0.001053 0.36141 0.04576 0.99451 0 1.60557 0.10667 1.34122 0.08911 0.58027 0.06254 0.48533 0.05231
