/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 55634.173929 0.001089 0.56146 0.15660 0.98667 1 0.24083 0.04014 0.19200 0.03200 0.13522 0.03024 0.10811 0.02417 55634.176210 0.001191 0.56959 0.15658 1.00000 1 0.22710 0.03796 0.17950 0.03000 0.12935 0.02823 0.10244 0.02235 55634.179318 0.001917 0.47002 0.09852 0.98249 1 0.27916 0.03342 0.22246 0.02663 0.13121 0.02258 0.10456 0.01799 55634.221927 0.001830 0.33603 0.08693 0.99206 1 0.23812 0.03096 0.19070 0.02480 0.08002 0.01789 0.06400 0.01431 55634.225094 0.001336 0.37166 0.09785 0.98913 1 0.29565 0.04108 0.23590 0.03278 0.10988 0.02457 0.08791 0.01966 55634.227331 0.000901 0.72513 0.20934 1.00000 1 0.23387 0.04420 0.18667 0.03528 0.16958 0.03701 0.13549 0.02957 55634.229437 0.001206 0.40501 0.10829 0.97590 1 0.30336 0.04389 0.24252 0.03508 0.12286 0.02763 0.09826 0.02209 55634.231804 0.001162 0.44227 0.11904 1.00000 1 0.28234 0.04229 0.22682 0.03397 0.12487 0.02792 0.10000 0.02236 55634.234274 0.001307 0.39623 0.10530 0.98889 1 0.28187 0.03995 0.22681 0.03214 0.11169 0.02511 0.08943 0.02010 55634.237585 0.002005 0.63444 0.13651 0.97303 1 0.20992 0.02831 0.16758 0.02260 0.13319 0.02233 0.10663 0.01788 55634.288707 0.001729 0.36152 0.09478 0.94958 1 0.23915 0.03225 0.19469 0.02625 0.08646 0.01944 0.07044 0.01583 55634.291452 0.001017 0.51085 0.14113 1.00000 1 0.27400 0.04445 0.22353 0.03626 0.13997 0.03130 0.11429 0.02556 55634.294473 0.002005 0.48338 0.09742 0.99971 1 0.27148 0.03165 0.22195 0.02588 0.13123 0.02157 0.10728 0.01764
