/* ** ** 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 57058.134520 0.000327 0.37974 0.06361 0.99115 0 2.73190 0.24149 2.34030 0.20685 1.03741 0.14760 0.88959 0.12657 57058.135214 0.000367 0.44717 0.07638 0.98425 0 2.08088 0.19932 1.78798 0.17125 0.93050 0.13160 0.80133 0.11333 57058.136004 0.000422 0.45526 0.06555 0.97945 0 2.51694 0.20329 2.17662 0.17581 1.14585 0.13657 0.99094 0.11810 57058.136753 0.000327 0.37813 0.06097 0.98230 0 2.99129 0.25390 2.58705 0.21959 1.13110 0.15506 0.97824 0.13411 57058.137387 0.000307 0.43048 0.07304 0.99057 0 2.56042 0.23999 2.21585 0.20769 1.10221 0.15588 0.95397 0.13491 57058.138026 0.000333 0.32761 0.05397 0.97391 0 3.13959 0.25605 2.70192 0.22031 1.02858 0.14723 0.88483 0.12666 57058.138666 0.000307 0.44616 0.07606 0.97170 0 2.52702 0.23627 2.18906 0.20467 1.12746 0.16072 0.97642 0.13919 57058.139317 0.000344 0.44784 0.07705 0.97479 0 2.20495 0.21043 1.90780 0.18207 0.98746 0.14135 0.85432 0.12229 57058.140338 0.000677 0.49941 0.05809 0.97009 0 2.29831 0.15644 1.99253 0.13562 1.14779 0.10826 0.99491 0.09384 57058.141368 0.000353 0.38880 0.06532 0.98361 0 2.46616 0.22037 2.13476 0.19076 0.95885 0.13642 0.83028 0.11813 57058.142063 0.000341 0.49573 0.08638 0.98305 0 1.99812 0.20102 1.73276 0.17433 0.99053 0.14093 0.85891 0.12220 57058.143764 0.001360 0.47748 0.03766 0.97660 0 2.54318 0.11441 2.20214 0.09907 1.21431 0.07868 1.05130 0.06812
