/* ** ** 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 55841.357135 0.000872 0.59350 0.16746 0.98333 1 0.33423 0.05689 0.23661 0.04012 0.19837 0.04464 0.13559 0.03032 55841.359009 0.001002 0.44304 0.11966 0.97101 1 0.39086 0.05921 0.26954 0.04083 0.17317 0.03872 0.11940 0.02670 55841.360752 0.000741 0.98150 0.31042 1.00000 1 0.23161 0.05180 0.16000 0.03578 0.22733 0.05084 0.15686 0.03508 55841.362103 0.000610 0.69686 0.20434 1.00000 1 0.39648 0.07521 0.27220 0.05163 0.27629 0.06178 0.19048 0.04259 55841.363308 0.000596 1.14119 0.37738 1.00000 1 0.24738 0.06000 0.17000 0.04123 0.28231 0.06346 0.19415 0.04364 55841.364979 0.001075 0.50489 0.13947 0.97297 1 0.31957 0.05131 0.21916 0.03519 0.16135 0.03627 0.11056 0.02485 55841.367041 0.000988 0.73758 0.18917 0.94035 1 0.33472 0.05675 0.22885 0.03880 0.24688 0.04751 0.16890 0.03250
