/* ** ** 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 56627.424495 0.000697 0.94424 0.28684 1.00000 1 0.23504 0.05036 0.19041 0.04080 0.22194 0.04779 0.18161 0.03911 56627.425904 0.000712 1.12187 0.37106 1.00000 1 0.17688 0.04290 0.14468 0.03509 0.19843 0.04462 0.16242 0.03652 56627.427603 0.000988 1.10055 0.35853 0.98529 1 0.13410 0.03161 0.10909 0.02571 0.14758 0.03318 0.11879 0.02671 56627.429172 0.000581 0.98185 0.31138 1.00000 1 0.24944 0.05609 0.20407 0.04588 0.24491 0.05477 0.20000 0.04472 56627.430842 0.001089 0.47506 0.12951 0.97333 1 0.28433 0.04433 0.23103 0.03602 0.13507 0.03021 0.10959 0.02451 56627.432963 0.001031 0.53350 0.14808 0.98592 1 0.26536 0.04363 0.21449 0.03526 0.14157 0.03166 0.11429 0.02556 56627.435040 0.001046 0.74446 0.19246 0.97064 1 0.25775 0.04449 0.20796 0.03589 0.19188 0.03693 0.15454 0.02974
