/* ** ** 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 55850.729831 0.000486 0.11970 0.02834 0.95238 0 3.13717 0.24372 2.09199 0.16252 0.37553 0.08397 0.25042 0.05599 55850.730708 0.000391 0.14976 0.03653 1.00000 0 2.93367 0.26272 1.95629 0.17519 0.43934 0.09969 0.29297 0.06647 55850.731452 0.000353 0.14793 0.03651 0.99180 0 3.27042 0.29073 2.18085 0.19387 0.48379 0.11140 0.32261 0.07429 55850.732253 0.000448 0.12747 0.03069 0.96774 0 3.10188 0.24964 2.06846 0.16647 0.39541 0.08972 0.26367 0.05983 55850.733373 0.000671 0.10232 0.02067 0.94088 0 3.63158 0.22263 2.42169 0.14846 0.37160 0.07151 0.24780 0.04769 55851.345211 0.000347 0.16199 0.03641 0.96667 0 2.80976 0.23561 2.45212 0.20562 0.45515 0.09490 0.39721 0.08282 55851.345908 0.000350 0.22048 0.05092 0.95868 0 2.06437 0.20494 1.80161 0.17886 0.45515 0.09490 0.39721 0.08282 55851.346756 0.000498 0.11755 0.02821 0.96512 0 2.32186 0.18116 2.02633 0.15810 0.27293 0.06195 0.23819 0.05406 55851.347708 0.000454 0.12579 0.02989 0.96178 0 2.41713 0.19460 2.10947 0.16983 0.30404 0.06799 0.26534 0.05933 55851.348669 0.000506 0.12015 0.02843 0.97143 0 2.24774 0.17422 1.96164 0.15205 0.27006 0.06039 0.23569 0.05270 55851.349788 0.000613 0.09583 0.02244 0.95755 0 2.36001 0.16419 2.05962 0.14329 0.22616 0.05057 0.19737 0.04413 55851.350897 0.000495 0.11142 0.02629 0.97076 0 2.48222 0.18687 2.16627 0.16308 0.27657 0.06184 0.24137 0.05397 55851.351921 0.000530 0.09529 0.02296 0.97268 0 2.63555 0.18585 2.30009 0.16220 0.25113 0.05787 0.21917 0.05051 55851.352960 0.000509 0.13095 0.02970 0.94318 0 2.32321 0.17967 2.02750 0.15680 0.30423 0.06486 0.26550 0.05661
