/* ** ** 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 54945.671510 0.000930 0.53607 0.14811 0.96875 1 0.29965 0.04861 0.24127 0.03914 0.16063 0.03592 0.12903 0.02885 54945.673151 0.000712 0.69590 0.20438 1.00000 1 0.28781 0.05439 0.23334 0.04410 0.20029 0.04503 0.16244 0.03652 54945.674822 0.000959 0.54402 0.15146 0.98485 1 0.28030 0.04649 0.22582 0.03745 0.15249 0.03410 0.12308 0.02752 54945.676638 0.000857 0.49041 0.13388 0.98305 1 0.35106 0.05497 0.28206 0.04417 0.17216 0.03850 0.13793 0.03084 54945.678119 0.000625 0.63905 0.18475 1.00000 1 0.35977 0.06592 0.29169 0.05345 0.22991 0.05141 0.18605 0.04160 54945.680690 0.001946 0.57065 0.11503 0.98921 1 0.25580 0.03102 0.20520 0.02488 0.14597 0.02350 0.11708 0.01885 54945.735615 0.001162 0.38314 0.10266 1.00000 1 0.32181 0.04628 0.25970 0.03735 0.12330 0.02787 0.09898 0.02237 54945.738041 0.001264 0.39671 0.10340 0.98851 1 0.30139 0.04188 0.24423 0.03394 0.11956 0.02636 0.09673 0.02133 54945.740176 0.000872 0.58933 0.16627 0.98333 1 0.28428 0.04891 0.22982 0.03954 0.16754 0.03746 0.13559 0.03032 54945.741789 0.000741 0.70959 0.21002 1.00000 1 0.27382 0.05270 0.22041 0.04242 0.19430 0.04369 0.15606 0.03508 54945.743634 0.001104 0.45991 0.12451 0.97368 1 0.28985 0.04424 0.23508 0.03588 0.13331 0.02981 0.10811 0.02417 54945.745769 0.001031 0.48314 0.13200 0.97183 1 0.29590 0.04646 0.23998 0.03768 0.14296 0.03197 0.11594 0.02593 54945.748035 0.001235 0.72979 0.18017 0.98673 1 0.23374 0.03803 0.18949 0.03083 0.17058 0.03168 0.13831 0.02568
