/* ** ** 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 57495.819663 0.000654 0.15159 0.03755 0.98230 0 3.11363 0.27678 1.27457 0.10886 0.47199 0.10912 0.18048 0.04036 57495.820745 0.000428 0.16464 0.04130 0.97297 0 3.41078 0.31781 1.64768 0.15266 0.56154 0.13079 0.27099 0.06243 57495.821986 0.000813 0.12373 0.02991 0.97865 0 2.58902 0.21196 1.18560 0.09680 0.32033 0.07285 0.14380 0.03263 57495.823451 0.000651 0.15625 0.03771 0.98667 0 2.52129 0.22845 1.16245 0.10528 0.39395 0.08812 0.18048 0.04036 57495.824423 0.000321 0.22626 0.05629 0.98198 0 3.55802 0.38800 1.61961 0.17663 0.80504 0.18003 0.36758 0.08219 57495.825054 0.000310 0.29393 0.07722 0.99065 0 2.79303 0.35246 1.25910 0.15885 0.82096 0.18917 0.36813 0.08481 57495.826072 0.000709 0.09952 0.02402 0.97143 0 3.67429 0.26608 1.64433 0.11903 0.36566 0.08418 0.16396 0.03777 57495.827403 0.000622 0.12533 0.02976 0.96279 0 3.41678 0.27281 1.54200 0.12306 0.42824 0.09577 0.19356 0.04328 57495.828372 0.000347 0.24786 0.06306 0.95000 0 3.12062 0.35815 1.39831 0.16046 0.77347 0.17563 0.34688 0.07872 57495.829993 0.001273 0.09708 0.01845 0.95650 0 3.39157 0.19307 1.51671 0.08630 0.32925 0.05972 0.14632 0.02653 57495.890633 0.000310 0.13052 0.03154 0.99065 0 3.32245 0.27370 2.85033 0.23478 0.43363 0.09850 0.37293 0.08467 57495.891435 0.000492 0.23115 0.03675 0.97059 0 2.99793 0.20738 2.59806 0.17971 0.69296 0.09920 0.60057 0.08598 57495.892439 0.000512 0.16562 0.03098 0.96610 0 2.75144 0.19554 2.38648 0.16961 0.45570 0.07886 0.39519 0.06838 57495.894036 0.001085 0.13974 0.01811 0.97600 0 3.09333 0.13989 2.68188 0.12129 0.43228 0.05250 0.37475 0.04551
