/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 57848.086049 0.000509 0.17061 0.01354 0.99432 0 14.21253 0.42366 13.05903 0.38927 2.42477 0.17835 2.22762 0.16385 57848.087033 0.000475 0.17919 0.01402 0.99390 0 14.70199 0.44685 13.53277 0.41130 2.63440 0.18998 2.42485 0.17487 57848.088008 0.000501 0.17990 0.01418 0.99422 0 13.80351 0.42331 12.71508 0.38993 2.48327 0.18026 2.28747 0.16605 57848.089027 0.000518 0.16117 0.01262 1.00000 0 14.80553 0.43366 13.63801 0.39946 2.38617 0.17322 2.19801 0.15956 57848.090114 0.000570 0.15796 0.01232 0.96954 0 14.15683 0.40398 13.04070 0.37213 2.23622 0.16233 2.05992 0.14953 57848.091176 0.000492 0.18008 0.01390 0.98777 0 14.47019 0.43545 13.32919 0.40112 2.60580 0.18527 2.40032 0.17066
