/* ** ** 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 57073.003457 0.001133 0.88310 0.26655 0.76428 1 0.19639 0.04095 0.15968 0.03330 0.17343 0.03785 0.14091 0.03075 57073.006464 0.001874 0.96553 0.23115 0.97817 1 0.14065 0.02377 0.11458 0.01937 0.13580 0.02302 0.11063 0.01876 57074.390816 0.000813 1.21925 0.40462 1.00000 1 0.15363 0.03841 0.12308 0.03077 0.18731 0.04088 0.15000 0.03273 57074.393038 0.001409 0.68338 0.19864 0.98969 1 0.15231 0.02828 0.12210 0.02267 0.10409 0.02328 0.08333 0.01863 57074.395624 0.001177 0.66688 0.19252 0.96296 1 0.19144 0.03495 0.15385 0.02809 0.12766 0.02855 0.10256 0.02293 57074.397527 0.000726 2.18255 0.87605 1.00000 1 0.09108 0.03036 0.07347 0.02449 0.19880 0.04445 0.16000 0.03578 57074.399807 0.001554 1.08353 0.27228 0.95209 1 0.14871 0.02680 0.11886 0.02142 0.16113 0.02822 0.12882 0.02256
