/* ** ** 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 56448.820631 0.000530 0.11865 0.02846 0.97268 0 2.19133 0.17016 1.87168 0.14532 0.26001 0.05901 0.22215 0.05042 56448.821931 0.000770 0.09083 0.02126 0.98120 0 1.96913 0.13636 1.68634 0.11677 0.17886 0.04000 0.15351 0.03433 56448.823450 0.000749 0.10327 0.02462 0.97297 0 1.78515 0.13041 1.52319 0.11126 0.18435 0.04184 0.15692 0.03561 56448.824775 0.000570 0.12180 0.02887 0.97970 0 1.99225 0.15678 1.70526 0.13419 0.24266 0.05426 0.20760 0.04642 56448.825843 0.000498 0.13104 0.03120 0.98256 0 2.10838 0.17235 1.81086 0.14803 0.27629 0.06178 0.23708 0.05301 56448.826881 0.000541 0.12424 0.02988 0.97861 0 2.03472 0.16224 1.74105 0.13881 0.25279 0.05737 0.21608 0.04904 56448.827914 0.000492 0.13838 0.03393 0.97059 0 2.00137 0.16817 1.71489 0.14409 0.27695 0.06380 0.23648 0.05448 56448.829486 0.001079 0.12487 0.02180 0.96783 0 1.91367 0.11220 1.64382 0.09638 0.23896 0.03928 0.20533 0.03376
