/* ** ** 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 54967.020394 0.002077 0.25973 0.06427 0.97203 1 0.29329 0.03293 0.23099 0.02593 0.07617 0.01680 0.05984 0.01319 54967.023952 0.001482 0.44857 0.12197 0.99020 1 0.22336 0.03415 0.17690 0.02704 0.10019 0.02253 0.07880 0.01772 54967.027133 0.001699 0.34919 0.09076 0.96581 1 0.25492 0.03377 0.20177 0.02673 0.08902 0.01991 0.07080 0.01583 54967.030373 0.001540 0.39874 0.10628 0.99057 1 0.23813 0.03410 0.18989 0.02719 0.09495 0.02135 0.07580 0.01704 54967.034004 0.002092 0.48586 0.11213 0.97459 1 0.20521 0.02718 0.16363 0.02167 0.09970 0.01884 0.07981 0.01508 54967.087215 0.001540 0.32672 0.08428 0.95283 1 0.30469 0.03852 0.24152 0.03053 0.09955 0.02238 0.07880 0.01772 54967.090556 0.001801 0.29056 0.07397 0.99359 1 0.28511 0.03469 0.22411 0.02726 0.08284 0.01852 0.06493 0.01452
