/* ** ** 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 58376.511329 0.000512 0.10802 0.02578 0.97740 0 2.67962 0.19803 2.11454 0.15626 0.28946 0.06567 0.22862 0.05187 58376.512443 0.000602 0.10066 0.02363 0.98077 0 2.45453 0.17572 1.95091 0.13967 0.24706 0.05524 0.19641 0.04392 58376.513569 0.000524 0.12638 0.03049 0.97790 0 2.22768 0.18287 1.76836 0.14516 0.28152 0.06388 0.22346 0.05070 58376.514876 0.000784 0.07732 0.01847 0.96310 0 2.43172 0.15514 1.92943 0.12309 0.18802 0.04329 0.14956 0.03444 58376.516222 0.000561 0.11916 0.02823 0.97423 0 2.23339 0.17495 1.77931 0.13938 0.26614 0.05951 0.21199 0.04740 58376.517478 0.000694 0.09232 0.02192 0.98333 0 2.28203 0.15979 1.81520 0.12710 0.21067 0.04780 0.16759 0.03803 58376.519144 0.000972 0.12767 0.02312 0.97024 0 2.10104 0.12849 1.67237 0.10227 0.26823 0.04572 0.21350 0.03639
