/* ** ** 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 56592.532611 0.000347 0.18404 0.04487 0.97500 0 2.15249 0.20902 1.85975 0.18059 0.39614 0.08858 0.34245 0.07657 56592.533328 0.000370 0.16850 0.04205 0.98438 0 2.15824 0.20645 1.83744 0.17575 0.36366 0.08383 0.30963 0.07135 56592.534237 0.000538 0.10382 0.02444 0.98387 0 2.45396 0.18057 2.11177 0.15539 0.25477 0.05697 0.21894 0.04896 56592.535342 0.000567 0.11242 0.02657 0.97449 0 2.19836 0.16805 1.85811 0.14205 0.24713 0.05526 0.20977 0.04691 56592.537058 0.001149 0.10940 0.01910 0.97711 0 2.05891 0.11327 1.73217 0.09529 0.22525 0.03733 0.18973 0.03144 56593.339543 0.000341 0.17282 0.04200 0.99153 0 2.30326 0.21899 1.98453 0.18869 0.39806 0.08901 0.34245 0.07657 56593.340304 0.000420 0.13419 0.03201 0.97931 0 2.45721 0.20404 2.10775 0.17500 0.32972 0.07373 0.28216 0.06309 56593.341074 0.000350 0.14615 0.03511 0.98347 0 2.67246 0.23456 2.30199 0.20202 0.39059 0.08734 0.33669 0.07529 56593.341997 0.000573 0.18732 0.03300 0.98990 0 2.44493 0.17272 2.11194 0.14918 0.45798 0.07390 0.39591 0.06389 56593.342957 0.000388 0.15777 0.03853 0.98507 0 2.19773 0.19799 1.89941 0.17112 0.34674 0.07871 0.29951 0.06799 56593.343759 0.000414 0.13448 0.03206 0.97902 0 2.47851 0.20472 2.11694 0.17483 0.33331 0.07453 0.28619 0.06399 56593.344636 0.000463 0.16318 0.03599 0.98125 0 2.18128 0.18215 1.87938 0.15693 0.35594 0.07266 0.30624 0.06251
