/* ** ** 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 55216.075900 0.001220 0.40640 0.10713 0.92857 1 0.31609 0.04351 0.25191 0.03467 0.12846 0.02888 0.10205 0.02294 55216.077977 0.000857 0.63189 0.18207 1.00000 1 0.26969 0.04861 0.21310 0.03840 0.17042 0.03831 0.13491 0.03033 55216.079808 0.000973 0.56454 0.15910 0.98507 1 0.27208 0.04666 0.21588 0.03702 0.15360 0.03435 0.12121 0.02710 55216.081740 0.000959 0.79352 0.23090 0.93939 1 0.21731 0.04183 0.17143 0.03299 0.17244 0.03763 0.13549 0.02957 55216.083395 0.000697 0.86883 0.26993 1.00000 1 0.23998 0.05117 0.19131 0.04079 0.20850 0.04712 0.16500 0.03729 55216.085444 0.001351 0.73140 0.17737 0.97867 1 0.22830 0.03610 0.17978 0.02843 0.16698 0.03070 0.13096 0.02408
