/* ** ** 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 54959.598859 0.001394 0.36437 0.09610 0.98958 1 0.28493 0.03930 0.22955 0.03166 0.10382 0.02334 0.08378 0.01884 54959.601067 0.000813 0.48013 0.13177 0.98214 1 0.37352 0.05880 0.30143 0.04745 0.17934 0.04032 0.14471 0.03253 54959.602635 0.000755 0.64990 0.18871 1.00000 1 0.29331 0.05433 0.23672 0.04385 0.19062 0.04262 0.15385 0.03440 54959.604466 0.001075 0.64066 0.15646 0.98245 1 0.29782 0.04607 0.24044 0.03720 0.19080 0.03606 0.15406 0.02911 54959.665646 0.001511 0.35165 0.09123 0.97115 1 0.27918 0.03673 0.22485 0.02958 0.09818 0.02195 0.07921 0.01771 54959.668479 0.001322 0.32831 0.08503 0.98901 1 0.33452 0.04371 0.27032 0.03532 0.10983 0.02456 0.08889 0.01988 54959.670352 0.000552 1.30754 0.44846 1.00000 1 0.19915 0.05179 0.16106 0.04188 0.26040 0.05823 0.21053 0.04708 54959.671907 0.001002 0.51024 0.12812 0.98080 1 0.34496 0.05044 0.27719 0.04053 0.17601 0.03593 0.14185 0.02896 54959.731785 0.000988 0.68814 0.20034 0.95588 1 0.22766 0.04244 0.18061 0.03366 0.15666 0.03503 0.12308 0.02752 54959.733514 0.000741 0.62849 0.18386 1.00000 1 0.31611 0.05870 0.24681 0.04583 0.19867 0.04491 0.15525 0.03509 54959.735518 0.001264 0.38283 0.09248 0.96602 1 0.37438 0.04780 0.29731 0.03796 0.14332 0.02939 0.11374 0.02332
