/* ** ** 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 56818.878794 0.000738 0.11673 0.02761 0.97647 0 1.61043 0.12395 1.37809 0.10606 0.18799 0.04204 0.16091 0.03598 56818.880284 0.000752 0.11242 0.02652 0.97308 0 1.63680 0.12305 1.40670 0.10575 0.18400 0.04115 0.15837 0.03541 56818.881939 0.000903 0.09252 0.02164 0.99038 0 1.63990 0.11251 1.40944 0.09670 0.15172 0.03393 0.12967 0.02899 56818.883354 0.000512 0.13011 0.03094 0.98305 0 2.08110 0.16813 1.77802 0.14365 0.27076 0.06055 0.23027 0.05149 56818.884893 0.001027 0.07509 0.01743 0.97746 0 1.79004 0.11099 1.53923 0.09543 0.13442 0.03006 0.11547 0.02582 56818.886496 0.000576 0.15652 0.03680 0.98995 0 1.59992 0.13982 1.36715 0.11947 0.25042 0.05465 0.21355 0.04660 56818.887720 0.000648 0.12102 0.02873 0.99107 0 1.74558 0.13924 1.49144 0.11896 0.21124 0.04724 0.18048 0.04036 56818.889314 0.000946 0.11370 0.02337 0.97859 0 1.72922 0.11381 1.47727 0.09721 0.19661 0.03829 0.16728 0.03258
