/* ** ** 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 60060.659685 0.000741 0.36798 0.09790 0.98039 1 1.72908 0.23960 0.42912 0.05946 0.63626 0.14450 0.15769 0.03581 60060.661080 0.000654 0.45160 0.12478 0.97778 1 1.61138 0.25357 0.39719 0.06250 0.72770 0.16527 0.17920 0.04070 60060.662358 0.000625 0.40755 0.10937 0.97674 1 1.86595 0.27196 0.46408 0.06764 0.76046 0.17137 0.18910 0.04261 60060.663723 0.000741 0.49572 0.13714 0.98039 1 1.30147 0.21199 0.32218 0.05248 0.64516 0.14427 0.16000 0.03578 60060.665248 0.000784 0.31411 0.08004 1.00000 1 1.97258 0.24841 0.48898 0.06157 0.61960 0.13726 0.15342 0.03398 60060.666817 0.000784 0.42823 0.11683 0.94444 1 1.46172 0.22095 0.36264 0.05481 0.62595 0.14217 0.15460 0.03511 60060.668110 0.000508 0.51214 0.14105 0.97143 1 1.85070 0.29755 0.45713 0.07349 0.94781 0.21195 0.23530 0.05261
