/* ** ** 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 56207.586657 0.000938 0.12417 0.02973 0.99383 0 1.57715 0.12898 0.98501 0.08015 0.19583 0.04407 0.12443 0.02782 56207.588358 0.000764 0.12861 0.03053 0.97348 0 1.84765 0.14691 1.22211 0.09715 0.23763 0.05315 0.15590 0.03486 56207.589869 0.000747 0.13140 0.03129 0.97674 0 1.85167 0.15157 1.20860 0.09893 0.24331 0.05441 0.15899 0.03555 56207.591926 0.001311 0.07703 0.01791 0.97792 0 1.83801 0.11660 1.18212 0.07498 0.14158 0.03166 0.09044 0.02022 56207.594389 0.001152 0.09635 0.02256 0.96482 0 1.67647 0.11646 1.08629 0.07546 0.16153 0.03612 0.10434 0.02333 56207.596726 0.001186 0.10478 0.02206 0.98537 0 1.81939 0.11938 1.18247 0.07758 0.19064 0.03813 0.12397 0.02479
