/* ** ** 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 56200.117046 0.000333 0.16278 0.03925 0.96522 0 2.57770 0.23256 2.21892 0.20017 0.41959 0.09383 0.36096 0.08071 56200.117908 0.000530 0.09716 0.02276 0.97268 0 2.67603 0.18640 2.31736 0.16142 0.26000 0.05814 0.22509 0.05033 56200.118793 0.000356 0.13086 0.03110 0.97561 0 2.95918 0.23843 2.55648 0.20598 0.38723 0.08659 0.33389 0.07466 56200.119557 0.000408 0.11711 0.02811 0.98582 0 2.83424 0.22083 2.43354 0.18962 0.33191 0.07535 0.28446 0.06457 56200.120347 0.000382 0.12605 0.02992 0.98485 0 2.82635 0.22536 2.44525 0.19498 0.35625 0.07966 0.30821 0.06892 56200.121279 0.000550 0.08909 0.02110 0.97895 0 2.75953 0.18671 2.38693 0.16150 0.24584 0.05580 0.21258 0.04825 56200.122396 0.000567 0.07739 0.01798 0.98980 0 3.13801 0.19774 2.67983 0.16886 0.24285 0.05431 0.20653 0.04618 56200.123594 0.000631 0.08123 0.01920 0.96789 0 2.70896 0.17870 2.31243 0.15256 0.22004 0.04993 0.18739 0.04253 56200.124606 0.000382 0.13235 0.03156 0.99242 0 2.71618 0.22471 2.30186 0.19042 0.35948 0.08039 0.30585 0.06839 56200.125362 0.000373 0.15312 0.03799 0.97674 0 2.34745 0.21561 2.02169 0.18567 0.35944 0.08284 0.30963 0.07135 56200.126076 0.000341 0.15087 0.03676 0.98305 0 2.63218 0.23294 2.25608 0.19963 0.39713 0.09014 0.34086 0.07737 56200.126872 0.000454 0.12222 0.02939 0.96815 0 2.52027 0.19960 2.12753 0.16848 0.30804 0.06993 0.26013 0.05904 56200.127888 0.000561 0.16272 0.02888 0.97423 0 2.81229 0.18788 2.41006 0.16099 0.45761 0.07524 0.39219 0.06448
