/* ** ** 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 56816.208605 0.000744 0.15778 0.03835 0.96109 0 2.70118 0.24458 1.02163 0.09192 0.42620 0.09613 0.16221 0.03627 56816.210240 0.000891 0.11958 0.02839 0.97727 0 3.25679 0.25920 1.11030 0.08834 0.38946 0.08710 0.13311 0.02976 56816.212248 0.001117 0.09607 0.02255 0.98705 0 3.22786 0.23027 1.09228 0.07792 0.31009 0.06935 0.10516 0.02351 56816.214010 0.000645 0.18127 0.04475 0.98655 0 2.87098 0.27927 0.99210 0.09650 0.52044 0.11809 0.17977 0.04079 56816.215677 0.001021 0.10070 0.02433 0.97167 0 3.26575 0.24073 1.12384 0.08279 0.32886 0.07568 0.11380 0.02621 56816.217974 0.001276 0.14109 0.02653 0.97279 0 3.14408 0.21126 1.08676 0.07302 0.44360 0.07792 0.15290 0.02685
