/* ** ** 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 54710.141103 0.000211 0.14814 0.03054 0.97607 0 6.02816 0.44516 5.12424 0.37841 0.89300 0.17186 0.75910 0.14609 54710.141823 0.000494 0.22795 0.05642 0.94118 1 4.36620 0.46337 1.09047 0.11573 0.99527 0.22256 0.25000 0.05590 54710.142985 0.000668 0.13499 0.03223 1.00000 1 5.13636 0.42968 1.28956 0.10788 0.69337 0.15504 0.17391 0.03889 54710.144133 0.000479 0.19889 0.04875 0.96970 1 5.03482 0.50560 1.25835 0.12637 1.00137 0.22392 0.25000 0.05590 54710.145062 0.000450 0.21195 0.05226 0.90323 1 5.29553 0.52943 1.34075 0.13404 1.12239 0.25299 0.28360 0.06392 54710.146355 0.000842 0.14814 0.02943 0.94453 1 5.66862 0.40028 1.42950 0.10094 0.83978 0.15595 0.21175 0.03932 54710.208564 0.000315 0.17965 0.02611 0.97752 0 6.61514 0.37551 5.91736 0.33589 1.18838 0.15902 1.06278 0.14222 54710.209477 0.000581 0.15907 0.03766 0.97500 1 5.41425 0.47542 1.33754 0.11743 0.86126 0.18935 0.21387 0.04703 54710.210508 0.000421 0.18385 0.04540 1.00000 1 5.93370 0.57437 1.48152 0.14340 1.09092 0.24786 0.27179 0.06175 54710.211423 0.000494 0.23725 0.05922 0.97059 1 4.11187 0.45588 1.02132 0.11322 0.97555 0.21815 0.24243 0.05421 54710.212411 0.000494 0.15719 0.03792 1.00000 1 6.04181 0.54682 1.49230 0.13505 0.94974 0.21239 0.23530 0.05261 54710.213370 0.000465 0.28677 0.05897 1.00000 1 5.37945 0.52979 1.34342 0.13230 1.54266 0.27850 0.38566 0.06962 54710.214299 0.000436 0.18084 0.04396 1.00000 1 5.94338 0.56656 1.47410 0.14052 1.07481 0.24035 0.26667 0.05963 54710.215244 0.000508 0.19863 0.04676 0.97143 1 5.29198 0.51017 1.29334 0.12468 1.05117 0.22576 0.25709 0.05521 54710.216202 0.000450 0.23073 0.05655 1.00000 1 4.78044 0.51778 1.16306 0.12597 1.10300 0.24251 0.26906 0.05916 54710.217132 0.000479 0.18894 0.04544 1.00000 1 5.47500 0.53380 1.34037 0.13066 1.03446 0.22743 0.25276 0.05558 54710.218512 0.000901 0.17742 0.03270 0.96425 1 5.42233 0.38837 1.31760 0.09436 0.96205 0.16337 0.23319 0.03960
