/* ** ** 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 58133.538017 0.000362 0.50909 0.09023 0.98400 0 2.03134 0.20767 1.56665 0.16015 1.03413 0.14971 0.79760 0.11547 58133.538893 0.000515 0.28251 0.04555 0.97753 0 2.56113 0.19831 2.03554 0.15760 0.72355 0.10233 0.57567 0.08141 58133.539903 0.000495 0.31205 0.05059 0.97076 0 2.41120 0.19106 1.93368 0.15322 0.75241 0.10641 0.60341 0.08534 58133.540930 0.000532 0.31861 0.05274 0.98913 0 2.12295 0.17359 1.70068 0.13906 0.67639 0.09735 0.54187 0.07799 58133.541906 0.000443 0.38154 0.06368 0.96732 0 2.23062 0.19695 1.79110 0.15815 0.85106 0.12054 0.68337 0.09679 58133.542829 0.000480 0.35028 0.05802 0.98795 0 2.16366 0.18363 1.73563 0.14730 0.75789 0.10781 0.60763 0.08643 58133.543879 0.000570 0.25445 0.04125 0.96954 0 2.51524 0.18346 2.01800 0.14719 0.64000 0.09266 0.51364 0.07436 58133.544770 0.000321 0.48655 0.08381 0.92793 0 2.47634 0.24055 1.98861 0.19317 1.20486 0.17139 0.96749 0.13762 58133.545621 0.000530 0.29785 0.04860 0.96721 0 2.34223 0.18364 1.88075 0.14745 0.69764 0.09982 0.56009 0.08014 58133.546674 0.000524 0.33253 0.05594 0.98343 0 2.05463 0.17305 1.64871 0.13886 0.68323 0.09950 0.54826 0.07985 58133.547655 0.000457 0.39821 0.06752 0.94937 0 2.05831 0.18454 1.65134 0.14805 0.81965 0.11797 0.65747 0.09463 58133.548694 0.000582 0.36150 0.05528 0.97512 0 2.10449 0.16550 1.68822 0.13277 0.76078 0.09977 0.61034 0.08005
