/* ** ** 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 55534.013113 0.000654 0.95379 0.30402 1.00000 1 0.22779 0.05120 0.18512 0.04161 0.21726 0.04910 0.17601 0.03977 55534.014987 0.001220 0.55948 0.15767 1.00000 1 0.20873 0.03580 0.17000 0.02916 0.11678 0.02611 0.09524 0.02130 55534.017137 0.000930 0.65913 0.19029 0.96875 1 0.24103 0.04401 0.19672 0.03592 0.15887 0.03553 0.12903 0.02885 55534.018865 0.000799 0.74377 0.22356 1.00000 1 0.24015 0.04823 0.19530 0.03922 0.17862 0.03994 0.14546 0.03252 55534.020536 0.000872 0.71185 0.20550 1.00000 1 0.24064 0.04548 0.19649 0.03713 0.17130 0.03738 0.14000 0.03055 55534.022119 0.000712 0.66358 0.19317 0.97959 1 0.30812 0.05743 0.25131 0.04684 0.20446 0.04572 0.16667 0.03727 55534.023746 0.000915 0.93368 0.29251 1.00000 1 0.16626 0.03628 0.13549 0.02957 0.15523 0.03489 0.12635 0.02840 55534.025460 0.000799 0.70444 0.20507 0.96364 1 0.26454 0.04930 0.21408 0.03990 0.18636 0.04167 0.15095 0.03375 55534.028394 0.002135 0.58110 0.11922 0.97675 1 0.22268 0.02784 0.18156 0.02270 0.12940 0.02105 0.10559 0.01718
