/* ** ** 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 59444.274295 0.001482 0.12750 0.02957 0.99020 1 1.72428 0.13543 0.65260 0.05124 0.21984 0.04798 0.08317 0.01815 59444.277185 0.001409 0.16075 0.03905 0.97938 1 1.39409 0.12742 0.52121 0.04763 0.22410 0.05045 0.08370 0.01884 59444.279625 0.001031 0.18779 0.04604 0.98592 1 1.63942 0.15928 0.60866 0.05913 0.30786 0.06930 0.11359 0.02556 59444.281659 0.001002 0.20365 0.04901 0.97101 1 1.63720 0.16117 0.61872 0.06090 0.33341 0.07322 0.12465 0.02737 59444.283693 0.001031 0.24188 0.05203 0.97970 1 1.70207 0.16346 0.63754 0.06122 0.41169 0.07925 0.15526 0.02988 59444.742358 0.002774 0.14878 0.02713 0.96472 1 1.47356 0.09557 0.51237 0.03322 0.21924 0.03736 0.07545 0.01285
