/* ** ** 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 54698.645917 0.005462 0.44917 0.09165 0.98563 1 0.14201 0.01620 0.08425 0.00960 0.06379 0.01079 0.03778 0.00639 54698.710054 0.002237 0.44155 0.11922 0.98701 1 0.18106 0.02708 0.11974 0.01789 0.07995 0.01797 0.05237 0.01177 54698.715515 0.003225 0.94286 0.24192 0.98016 1 0.08955 0.01608 0.05778 0.01038 0.08443 0.01547 0.05497 0.01007 54698.779943 0.005462 0.44363 0.10955 0.98297 1 0.10504 0.01447 0.05897 0.00811 0.04660 0.00955 0.02589 0.00530 54698.842924 0.001772 0.51790 0.14271 0.98361 1 0.16090 0.02590 0.12934 0.02082 0.08333 0.01863 0.06667 0.01491 54698.846004 0.001307 0.64862 0.18629 0.98889 1 0.17441 0.03143 0.13888 0.02503 0.11313 0.02530 0.08989 0.02010 54698.849693 0.002382 0.47718 0.10770 0.97924 1 0.18759 0.02406 0.15075 0.01933 0.08951 0.01662 0.07223 0.01341 54698.906520 0.002164 0.47543 0.12982 0.99329 1 0.15116 0.02367 0.11361 0.01779 0.07186 0.01607 0.05405 0.01209 54698.910922 0.002237 0.45724 0.12465 0.98052 1 0.15487 0.02362 0.11467 0.01749 0.07081 0.01600 0.05246 0.01185 54698.916281 0.003123 0.40404 0.09793 0.99070 1 0.15071 0.01969 0.11200 0.01463 0.06089 0.01243 0.04507 0.00920
