/* ** ** 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 58011.480167 0.000544 0.11784 0.01804 0.98404 0 5.43446 0.26891 4.50332 0.22284 0.64040 0.09276 0.53005 0.07678 58011.481258 0.000547 0.13331 0.02010 0.98942 0 4.95152 0.25885 4.02324 0.21031 0.66006 0.09335 0.53565 0.07575 58011.482117 0.000312 0.08216 0.01911 0.97222 0 5.73728 0.36829 4.64232 0.29800 0.47140 0.10541 0.38159 0.08533 58011.483005 0.000576 0.11587 0.01754 0.98492 0 5.35721 0.26363 4.36182 0.21462 0.62073 0.08884 0.50568 0.07237 58011.484209 0.000628 0.10197 0.01634 0.99539 0 4.82783 0.23769 3.91112 0.19256 0.49231 0.07508 0.39881 0.06082 58011.485488 0.000651 0.11079 0.01652 0.96444 0 5.15215 0.24027 4.20152 0.19593 0.57081 0.08086 0.46597 0.06602 58011.486828 0.000689 0.10554 0.01646 0.97059 0 4.61746 0.22142 3.75786 0.18020 0.48731 0.07233 0.39665 0.05886 58011.488043 0.000527 0.14193 0.02160 0.97253 0 4.89261 0.26065 4.00966 0.21360 0.69441 0.09898 0.56830 0.08099 58011.489232 0.000663 0.10148 0.01524 0.97817 0 5.37386 0.24379 4.35708 0.19765 0.54536 0.07805 0.44247 0.06333 58011.490204 0.000310 0.09669 0.02212 0.99065 0 5.01170 0.34370 4.11415 0.28211 0.48460 0.10576 0.39689 0.08661 58011.490908 0.000394 0.07276 0.01685 0.97059 0 5.10865 0.30800 4.18691 0.25241 0.37168 0.08311 0.30354 0.06787 58011.491619 0.000318 0.10857 0.02557 0.97273 0 4.24033 0.31325 3.44827 0.25471 0.46039 0.10295 0.37446 0.08373 58011.492259 0.000321 0.10172 0.02388 0.97297 0 4.46887 0.31980 3.63718 0.26028 0.45458 0.10166 0.37099 0.08296 58011.492884 0.000304 0.11710 0.02769 0.96190 0 4.16701 0.32048 3.38554 0.26040 0.48795 0.10912 0.39670 0.08870 58011.493587 0.000394 0.08083 0.01907 0.98529 0 4.49886 0.28833 3.66696 0.23499 0.36364 0.08255 0.29507 0.06698 58011.494386 0.000405 0.09798 0.01976 0.97143 0 4.99197 0.30117 4.05485 0.24463 0.48910 0.09413 0.39772 0.07654 58011.495653 0.000862 0.12657 0.01695 0.96309 0 4.25432 0.19089 3.50091 0.15706 0.53845 0.06795 0.44307 0.05590
