/* ** ** 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 57589.957860 0.000307 0.37142 0.06209 0.97170 0 3.05448 0.26376 2.59589 0.22418 1.13450 0.16238 0.96220 0.13772 57589.958499 0.000333 0.35375 0.05858 0.96522 0 2.96933 0.25162 2.53784 0.21506 1.05041 0.14945 0.89763 0.12771 57589.959370 0.000538 0.45630 0.05834 0.97312 0 2.54650 0.18299 2.17620 0.15638 1.16195 0.12289 0.99320 0.10504 57589.960855 0.000946 0.50238 0.04365 0.97554 0 2.92272 0.14709 2.49681 0.12565 1.46832 0.10398 1.25435 0.08883 57589.962154 0.000353 0.34625 0.05773 0.98361 0 2.81884 0.23980 2.40787 0.20484 0.97604 0.13995 0.83374 0.11955 57589.963523 0.001016 0.51188 0.04461 0.98006 0 2.69122 0.13727 2.28902 0.11676 1.37759 0.09736 1.17175 0.08281 57589.964848 0.000304 0.41503 0.07187 0.99048 0 2.67436 0.25368 2.26820 0.21519 1.10993 0.16080 0.94275 0.13659 57589.965447 0.000295 0.36298 0.06096 0.99020 0 3.20299 0.28136 2.70432 0.23754 1.16262 0.16641 0.98125 0.14045 57589.966879 0.001137 0.46582 0.03873 0.98473 0 2.79833 0.13190 2.37900 0.11213 1.30353 0.08928 1.10885 0.07594
