/* ** ** 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 55500.019171 0.000312 0.14264 0.03413 0.98148 0 3.18848 0.27136 2.64056 0.22468 0.45482 0.10171 0.37799 0.08452 55500.019880 0.000396 0.10151 0.02383 0.95620 0 3.64285 0.26010 3.00400 0.21443 0.36977 0.08269 0.30585 0.06839 55500.020745 0.000469 0.08612 0.02007 0.97531 0 3.54747 0.23258 2.94797 0.19326 0.30551 0.06832 0.25359 0.05670 55500.021596 0.000376 0.12503 0.03014 0.96923 0 3.02643 0.24573 2.50702 0.20354 0.37841 0.08589 0.31391 0.07122 55500.022418 0.000446 0.09200 0.02179 0.95455 0 3.55527 0.24202 2.92073 0.19881 0.32708 0.07421 0.26906 0.06105 55500.023514 0.000651 0.17611 0.02722 0.98222 0 3.10606 0.18776 2.55888 0.15468 0.54702 0.07783 0.45092 0.06414 55500.024839 0.000668 0.15912 0.02477 0.97835 0 3.30647 0.18904 2.72741 0.15593 0.52614 0.07616 0.43411 0.06285 55500.025982 0.000475 0.08878 0.02131 0.97561 0 3.31459 0.22461 2.74606 0.18606 0.29426 0.06777 0.24399 0.05618 55500.026920 0.000463 0.10068 0.02362 0.96875 0 3.11148 0.22099 2.57031 0.18254 0.31326 0.07005 0.25850 0.05780 55500.027692 0.000310 0.14485 0.03470 0.97196 0 3.20239 0.27493 2.66411 0.22870 0.46386 0.10373 0.38526 0.08615 55500.028416 0.000414 0.10480 0.02468 0.97203 0 3.33913 0.24649 2.75214 0.20314 0.34993 0.07825 0.28825 0.06445 55500.029171 0.000341 0.12168 0.02967 0.97458 0 3.35685 0.26969 2.78700 0.22387 0.40845 0.09404 0.33946 0.07816 55500.030722 0.001204 0.12928 0.01721 0.92788 0 3.15167 0.14064 2.62842 0.11729 0.40744 0.05110 0.33974 0.04261
