/* ** ** 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 56826.337088 0.001065 0.08039 0.01871 0.97011 0 1.62502 0.10472 1.39223 0.08971 0.13063 0.02921 0.11223 0.02510 56826.338980 0.000828 0.09331 0.02185 0.97203 0 1.79244 0.12442 1.54533 0.10726 0.16726 0.03740 0.14412 0.03223 56826.340739 0.000932 0.08585 0.02065 0.97205 0 1.68929 0.11435 1.45471 0.09846 0.14502 0.03347 0.12458 0.02873 56826.342464 0.000793 0.09695 0.02306 0.96715 0 1.79106 0.12679 1.53635 0.10875 0.17364 0.03943 0.14917 0.03387 56826.343772 0.000515 0.19171 0.04574 0.96629 0 1.49274 0.14393 1.27613 0.12303 0.28618 0.06245 0.24459 0.05337 56826.344747 0.000460 0.19979 0.04912 0.98113 0 1.51350 0.15463 1.29324 0.13213 0.30239 0.06762 0.25684 0.05743 56826.346194 0.000987 0.12802 0.02621 0.98534 0 1.46469 0.10231 1.25325 0.08754 0.18751 0.03609 0.16098 0.03098
