/* ** ** 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 56275.525963 0.001120 0.41179 0.11170 0.96382 0 0.54859 0.08261 0.24931 0.03685 0.22591 0.05097 0.10742 0.02402 56275.528162 0.001079 0.46338 0.12682 0.95442 0 0.50113 0.07901 0.24023 0.03786 0.23221 0.05195 0.11255 0.02517 56275.530008 0.000767 0.81574 0.24973 0.96981 0 0.39205 0.08133 0.19183 0.03977 0.31981 0.07201 0.15500 0.03487 56275.531437 0.000663 0.80996 0.24728 0.96507 0 0.47017 0.09759 0.22563 0.04677 0.38082 0.08525 0.18130 0.04054 56275.532705 0.000605 0.90801 0.28232 0.95215 0 0.46265 0.09984 0.22024 0.04749 0.42009 0.09403 0.20134 0.04502 56275.534713 0.001403 0.54786 0.13074 0.97320 0 0.43673 0.06294 0.21051 0.03030 0.23927 0.04551 0.11835 0.02246
