/* ** ** 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 57654.063931 0.000394 0.18100 0.04408 0.98529 0 1.89303 0.18267 1.65201 0.15941 0.34263 0.07661 0.29900 0.06686 57654.064738 0.000414 0.16586 0.04072 0.97203 0 1.96385 0.18264 1.71380 0.15938 0.32572 0.07400 0.28425 0.06458 57654.065545 0.000388 0.18412 0.04549 0.96269 0 1.90621 0.18514 1.66350 0.16156 0.35097 0.07974 0.30628 0.06958 57654.066515 0.000582 0.12212 0.02899 0.98010 0 1.90837 0.15189 1.66539 0.13255 0.23306 0.05211 0.20338 0.04548 57654.068277 0.001181 0.10460 0.01922 0.97460 0 1.84591 0.10497 1.61088 0.09161 0.19308 0.03374 0.16850 0.02944 57654.243176 0.000440 0.15689 0.03781 0.95395 0 2.10166 0.18902 1.76122 0.15840 0.32973 0.07373 0.27632 0.06179 57654.243963 0.000347 0.20081 0.04927 0.95833 0 2.07039 0.20908 1.73502 0.17521 0.41575 0.09297 0.34841 0.07791 57654.244669 0.000359 0.17425 0.04234 0.97581 0 2.26764 0.21563 1.90031 0.18070 0.39514 0.08836 0.33113 0.07404 57654.245600 0.000573 0.14816 0.03664 0.98485 0 1.61065 0.14406 1.34974 0.12073 0.23864 0.05502 0.19998 0.04611 57654.246714 0.000541 0.11538 0.02809 0.97861 0 2.20400 0.17219 1.84698 0.14430 0.25429 0.05863 0.21310 0.04913 57654.247869 0.000613 0.11965 0.02835 0.95283 0 1.97823 0.15494 1.65778 0.12984 0.23669 0.05293 0.19835 0.04435 57654.249567 0.001085 0.09935 0.01945 0.95733 0 2.00626 0.11684 1.68127 0.09791 0.19932 0.03725 0.16703 0.03121
