/* ** ** 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 55136.970057 0.001772 0.13970 0.03364 0.99180 1 1.29799 0.11058 0.46172 0.03931 0.18133 0.04084 0.06572 0.01479 55136.973412 0.001583 0.14621 0.03524 0.98165 1 1.40515 0.12107 0.50807 0.04378 0.20545 0.04625 0.07431 0.01672 55136.976390 0.001394 0.18251 0.04497 0.97917 1 1.28167 0.12395 0.45970 0.04445 0.23392 0.05301 0.08407 0.01904 55136.979992 0.002208 0.12034 0.02848 0.98026 1 1.24076 0.09618 0.44606 0.03457 0.14932 0.03339 0.05369 0.01201 55136.984844 0.002644 0.15669 0.03130 0.96862 1 1.16855 0.08605 0.42155 0.03104 0.18310 0.03400 0.06580 0.01222 55137.523013 0.001264 0.24198 0.05960 0.98743 1 1.55183 0.17227 0.40109 0.04453 0.37551 0.08256 0.09710 0.02135 55137.588093 0.002876 0.13311 0.02710 0.98882 1 1.76469 0.12403 0.42399 0.02980 0.23490 0.04488 0.05662 0.01082 55137.690721 0.034947 0.17114 0.03052 0.08024 1 1.75065 0.12076 0.44588 0.03075 0.29961 0.04926 0.07666 0.01260
