/* ** ** 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 57341.390763 0.000668 0.17298 0.04227 0.97826 1 4.48891 0.42461 1.02210 0.09667 0.77650 0.17498 0.17651 0.03977 57341.392099 0.000668 0.18207 0.04430 0.97826 1 4.22843 0.40543 0.97272 0.09326 0.76989 0.17216 0.17778 0.03975 57341.393494 0.000726 0.16646 0.04046 0.96000 1 4.29805 0.39192 0.99363 0.09060 0.71546 0.16121 0.16548 0.03729 57341.395106 0.000886 0.10753 0.02533 0.98361 1 5.38081 0.39900 1.24071 0.09200 0.57857 0.12938 0.13333 0.02981 57341.396617 0.000625 0.15537 0.03767 1.00000 1 5.16861 0.46288 1.18913 0.10649 0.80305 0.18094 0.18472 0.04162 57341.397866 0.000625 0.16957 0.04131 0.97674 1 4.84848 0.44925 1.11704 0.10350 0.82216 0.18525 0.18912 0.04261 57341.399246 0.000755 0.12122 0.02844 1.00000 1 5.72004 0.44361 1.31545 0.10202 0.69337 0.15352 0.15935 0.03528 57341.400495 0.000494 0.23836 0.06034 1.00000 1 4.23897 0.47456 0.97492 0.10915 1.01038 0.22943 0.23195 0.05267 57341.402209 0.001220 0.16093 0.03132 0.97271 1 4.06736 0.29597 0.93830 0.06827 0.65457 0.11814 0.15106 0.02727
