/* ** ** 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 55125.597247 0.000321 0.21794 0.05392 0.97297 0 2.49875 0.25689 1.83867 0.18803 0.54457 0.12256 0.38469 0.08514 55125.597930 0.000362 0.16609 0.04031 0.95200 0 2.76648 0.26030 2.00096 0.18821 0.45949 0.10281 0.33670 0.07529 55125.598876 0.000584 0.20185 0.03571 0.97030 0 2.78271 0.20182 1.96657 0.14262 0.56169 0.09064 0.39595 0.06389 55125.599823 0.000362 0.21628 0.04934 0.96800 0 2.60752 0.25137 1.81892 0.17531 0.56397 0.11660 0.39303 0.08123 55125.600560 0.000376 0.12968 0.03126 0.95385 0 3.46132 0.28126 2.45898 0.19979 0.44887 0.10187 0.31889 0.07238 55125.601385 0.000448 0.19904 0.03991 0.97419 0 2.79540 0.23156 1.99858 0.16555 0.55640 0.10159 0.39801 0.07267 55125.602479 0.000645 0.24320 0.03823 0.96861 0 2.69378 0.18809 1.93270 0.13494 0.65511 0.09227 0.47058 0.06628 55125.603451 0.000327 0.16660 0.04192 0.93805 0 3.06035 0.28314 2.19024 0.20257 0.50987 0.11931 0.36316 0.08495 55125.604172 0.000394 0.18128 0.04494 0.98529 0 2.29953 0.22897 1.62742 0.16201 0.41687 0.09465 0.29509 0.06697 55125.604944 0.000379 0.19840 0.04931 0.96183 0 2.20818 0.22363 1.58090 0.16011 0.43811 0.09944 0.31383 0.07123 55125.605711 0.000388 0.15146 0.03694 0.95522 0 2.86765 0.25634 2.04125 0.18245 0.43434 0.09857 0.30893 0.07011 55125.606553 0.000454 0.13900 0.03359 0.95541 0 2.64711 0.21979 1.89596 0.15742 0.36795 0.08351 0.26362 0.05983 55125.607664 0.000657 0.16758 0.02863 0.96035 0 3.08355 0.19960 2.19049 0.14178 0.51675 0.08172 0.36758 0.05812
