/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 56818.138076 0.000981 0.08826 0.02061 0.98525 0 1.58210 0.10650 1.35853 0.09144 0.13964 0.03123 0.11996 0.02682 56818.139954 0.000897 0.09501 0.02225 0.96452 0 1.63653 0.11383 1.41207 0.09822 0.15549 0.03477 0.13400 0.02996 56818.141933 0.001082 0.07501 0.01741 0.98663 0 1.67568 0.10415 1.44866 0.09004 0.12569 0.02810 0.10858 0.02428 56818.143634 0.000619 0.16234 0.03977 0.97664 0 1.34559 0.12369 1.16500 0.10709 0.21844 0.04960 0.18911 0.04295 56818.145217 0.000964 0.09347 0.02189 0.97598 0 1.53795 0.10671 1.32153 0.09170 0.14375 0.03215 0.12328 0.02757 56818.147300 0.001120 0.12526 0.02418 0.98708 0 1.51610 0.09769 1.30507 0.08408 0.18991 0.03456 0.16356 0.02977
