/* ** ** 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 59679.253939 0.002992 0.12191 0.02640 0.99407 1 1.51615 0.10948 0.38446 0.02776 0.18483 0.03773 0.04688 0.00957 59679.721127 0.003864 0.11354 0.02155 0.99516 1 1.62053 0.09958 0.41291 0.02537 0.18400 0.03305 0.04684 0.00841 59680.186973 0.002295 0.11252 0.02659 0.98102 1 1.80026 0.13757 0.45893 0.03507 0.20257 0.04530 0.05161 0.01154 59680.192551 0.003283 0.12554 0.02533 0.98490 1 1.55525 0.10545 0.39783 0.02697 0.19524 0.03711 0.05005 0.00951 59680.636398 0.001162 0.15246 0.03673 1.00000 1 1.63820 0.14657 0.66057 0.05909 0.24976 0.05586 0.10000 0.02236 59680.639956 0.002397 0.12996 0.02302 0.97707 1 1.68808 0.10119 0.68779 0.04122 0.21939 0.03657 0.08932 0.01489
