/* ** ** 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 59317.535341 0.000336 0.32670 0.08560 0.98276 0 1.52391 0.20723 1.06485 0.14449 0.49786 0.11150 0.35146 0.07859 59317.536209 0.000532 0.52483 0.09230 0.96739 0 1.47225 0.15485 1.08232 0.11384 0.77267 0.10890 0.57107 0.08043 59317.537091 0.000350 0.27871 0.07186 0.97521 0 1.60278 0.19627 1.20488 0.14755 0.44672 0.10136 0.33514 0.07605 59317.538043 0.000602 0.48489 0.08506 0.98558 0 1.34760 0.13827 1.00034 0.10264 0.65344 0.09298 0.48608 0.06915 59317.539027 0.000382 0.22815 0.05666 0.94697 0 1.91195 0.20646 1.40974 0.15218 0.43621 0.09756 0.32053 0.07167 59317.539996 0.000587 0.39687 0.06839 0.97044 0 1.70560 0.15930 1.25231 0.11695 0.67691 0.09802 0.49791 0.07210 59317.541125 0.000541 0.44777 0.07673 0.96791 0 1.66290 0.16086 1.23578 0.11950 0.74460 0.10532 0.55341 0.07826 59317.542288 0.000622 0.37586 0.06447 0.97209 0 1.68397 0.15244 1.24849 0.11299 0.63294 0.09222 0.46683 0.06801 59317.543460 0.000550 0.41261 0.07035 0.98421 0 1.72295 0.16407 1.29367 0.12318 0.71091 0.10055 0.53565 0.07575 59317.544340 0.000330 0.46487 0.12614 0.93860 0 1.08093 0.16604 0.80022 0.12287 0.50250 0.11239 0.37446 0.08373 59317.545242 0.000573 0.33059 0.06331 0.99495 0 1.56403 0.15511 1.18143 0.11712 0.51705 0.08470 0.38869 0.06367
