/* ** ** 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 55495.686680 0.000394 0.08254 0.01872 0.95588 0 4.58837 0.28212 3.94171 0.24233 0.37873 0.08266 0.32362 0.07062 55495.687378 0.000304 0.12840 0.03051 0.96190 0 3.61367 0.29012 3.09816 0.24870 0.46400 0.10376 0.39670 0.08870 55495.688069 0.000388 0.09029 0.02107 0.96269 0 3.97872 0.26621 3.44686 0.23062 0.35922 0.08033 0.31059 0.06945 55495.688767 0.000310 0.11037 0.02542 0.99065 0 4.20271 0.30971 3.60205 0.26541 0.46387 0.10123 0.39689 0.08661 55495.689753 0.000677 0.13040 0.01960 0.96154 0 3.99536 0.20344 3.40993 0.17362 0.52100 0.07369 0.44519 0.06296 55495.690812 0.000382 0.08701 0.02029 0.97727 0 4.19570 0.27849 3.57685 0.23742 0.36505 0.08163 0.31059 0.06945 55495.691562 0.000367 0.08665 0.02021 0.97638 0 4.35311 0.28898 3.72107 0.24699 0.37722 0.08436 0.32312 0.07225 55495.692268 0.000339 0.09454 0.02214 0.96581 0 4.38580 0.30511 3.74520 0.26056 0.41464 0.09272 0.35457 0.07928 55495.693252 0.000645 0.11475 0.01847 0.96861 0 4.08088 0.20975 3.47412 0.17856 0.46826 0.07142 0.39881 0.06082 55495.694201 0.000304 0.11877 0.02852 0.97143 0 3.81335 0.29837 3.24842 0.25414 0.45292 0.10282 0.38755 0.08799 55495.695075 0.000570 0.15567 0.02385 0.98985 0 3.84130 0.21792 3.28427 0.18630 0.59799 0.08509 0.51092 0.07270 55495.695957 0.000312 0.11232 0.02695 1.00000 0 3.81522 0.29580 3.24374 0.25147 0.42853 0.09732 0.36602 0.08310 55495.696611 0.000341 0.10847 0.02488 0.94068 0 4.12443 0.29182 3.49074 0.24697 0.44738 0.09763 0.37901 0.08271 55495.697777 0.000825 0.09374 0.01460 0.96842 0 4.03796 0.18273 3.48322 0.15762 0.37850 0.05643 0.32663 0.04869
