/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55897.003471 0.001148 0.70187 0.20678 0.60065 1 0.42940 0.08177 0.23940 0.04558 0.30138 0.06775 0.16775 0.03771 55897.005258 0.000639 1.14157 0.37212 0.95455 1 0.30001 0.07114 0.16652 0.03948 0.34248 0.07660 0.19048 0.04259 55897.006841 0.000944 0.99466 0.31464 0.98462 1 0.22085 0.04940 0.12500 0.02795 0.21967 0.04913 0.12500 0.02795 55897.008889 0.001104 0.50566 0.13872 0.96053 1 0.38061 0.05976 0.21760 0.03416 0.19246 0.04329 0.10904 0.02451 55897.011155 0.001162 0.75082 0.22154 0.97500 1 0.24076 0.04634 0.13671 0.02631 0.18077 0.04043 0.10256 0.02293 55897.013101 0.000784 0.99656 0.31606 0.98148 1 0.27047 0.06082 0.15308 0.03441 0.26954 0.06028 0.15094 0.03375 55897.014917 0.001031 0.65496 0.17576 0.97665 1 0.37079 0.06419 0.21063 0.03646 0.24285 0.04980 0.13787 0.02827
