/* ** ** 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 57990.034138 0.000446 0.11509 0.02729 0.98701 0 3.19762 0.25182 2.25038 0.17703 0.36801 0.08231 0.26360 0.05894 57990.035032 0.000448 0.18138 0.04549 0.97419 0 2.11592 0.20949 1.42340 0.14090 0.38380 0.08845 0.25841 0.05953 57990.036215 0.000735 0.08720 0.02037 0.96850 0 2.74600 0.18565 1.86689 0.12621 0.23946 0.05355 0.16287 0.03642 57990.037445 0.000495 0.13554 0.03236 0.98246 0 2.59468 0.21680 1.76167 0.14720 0.35167 0.07864 0.23849 0.05333 57990.038423 0.000483 0.17680 0.04013 0.97574 0 2.36069 0.21173 1.59954 0.14345 0.41738 0.08703 0.28277 0.05896 57990.369458 0.000475 0.12782 0.03085 0.99390 0 2.21852 0.18212 1.89790 0.15579 0.28357 0.06436 0.24258 0.05506 57990.370974 0.001042 0.06683 0.01528 0.97222 0 2.08666 0.11993 1.77939 0.10227 0.13945 0.03086 0.11870 0.02627 57990.372583 0.000567 0.11951 0.02917 0.98980 0 1.98443 0.15947 1.69272 0.13602 0.23715 0.05466 0.20110 0.04634 57990.374082 0.000932 0.08446 0.01842 0.98092 0 2.08016 0.12736 1.77082 0.10840 0.17570 0.03677 0.14889 0.03116 57990.428313 0.000778 0.09784 0.02297 0.98141 0 2.63837 0.18460 1.58723 0.11068 0.25814 0.05785 0.15177 0.03394 57990.429626 0.000535 0.12855 0.03058 0.96216 0 3.13811 0.25481 1.74634 0.14180 0.40340 0.09021 0.22509 0.05033 57990.430847 0.000686 0.08953 0.02093 0.97046 0 3.40812 0.23154 1.92421 0.13068 0.30514 0.06826 0.17420 0.03895 57990.432424 0.000891 0.10138 0.02174 0.97078 0 2.83979 0.18646 1.59991 0.10505 0.28790 0.05879 0.16080 0.03282
