/* ** ** 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 56296.936944 0.000642 0.10922 0.00823 0.98198 0 18.12567 0.42633 16.69024 0.39254 1.97962 0.14181 1.82140 0.13048 56296.938298 0.000712 0.10307 0.00791 0.98780 0 17.07733 0.39462 15.72445 0.36332 1.76022 0.12875 1.62087 0.11857 56296.939684 0.000674 0.10899 0.00820 0.99142 0 17.12187 0.40259 15.85070 0.37270 1.86611 0.13335 1.72757 0.12345 56296.941078 0.000720 0.10107 0.00773 0.96787 0 17.37111 0.39366 16.08026 0.36440 1.75562 0.12827 1.62516 0.11874 56296.942502 0.000703 0.10393 0.00787 0.97942 0 17.31574 0.40079 15.98487 0.36998 1.79967 0.12977 1.66078 0.11976 56296.943888 0.000683 0.10090 0.00787 0.98729 0 17.82762 0.41138 16.40890 0.37862 1.79883 0.13405 1.65778 0.12354 56296.945340 0.000770 0.09709 0.00733 0.97744 0 16.91590 0.37670 15.65884 0.34871 1.64231 0.11843 1.52025 0.10963 56296.947363 0.001253 0.10821 0.00603 0.98845 0 17.53312 0.29975 16.22961 0.27747 1.89733 0.10059 1.75627 0.09311
