/* ** ** 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 53691.809288 0.000098 0.16991 0.06959 0.96554 0 2.90895 0.45877 2.51397 0.39648 0.49426 0.18681 0.42716 0.16145 53691.839623 0.030223 0.13642 0.02615 0.06195 1 2.76865 0.18503 0.70541 0.04714 0.37770 0.06785 0.09619 0.01728 53691.866305 0.000321 0.13247 0.03199 0.96396 0 3.22442 0.26287 2.78626 0.22715 0.42714 0.09710 0.36908 0.08390 53691.867199 0.000573 0.10322 0.02034 0.91187 0 3.61823 0.21649 3.08506 0.18455 0.37347 0.07014 0.31858 0.05983 53691.871676 0.001830 0.08504 0.01983 0.95016 1 3.03240 0.20051 0.78670 0.05202 0.25789 0.05767 0.06682 0.01494 53691.875293 0.001787 0.10392 0.02229 0.97537 1 2.97136 0.19601 0.76992 0.05079 0.30878 0.06303 0.08002 0.01633 53691.943411 0.000307 0.07841 0.02351 0.97498 0 3.43983 0.27874 2.97322 0.24093 0.26972 0.07786 0.23260 0.06715
