/* ** ** 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 55196.434788 0.000503 0.25605 0.00926 1.00000 0 53.47911 0.87154 44.54686 0.72593 13.69308 0.44221 11.40627 0.36837 55196.435806 0.000515 0.24845 0.00904 1.00000 0 53.04592 0.85753 44.52210 0.71972 13.17911 0.42961 11.06627 0.36072 55196.436813 0.000492 0.25281 0.00916 1.00000 0 54.85022 0.89439 46.01426 0.75031 13.86665 0.44871 11.62752 0.37630 55196.437826 0.000521 0.24117 0.00874 1.00000 0 53.99561 0.86053 45.58223 0.72635 13.02206 0.42359 10.98783 0.35740 55196.438833 0.000486 0.25688 0.00924 0.99405 0 55.12170 0.89326 46.46523 0.75292 14.15994 0.45484 11.93185 0.38318 55196.439831 0.000512 0.24173 0.00872 1.00000 0 55.01003 0.87798 46.18253 0.73705 13.29733 0.43021 11.16767 0.36142 55196.440856 0.000512 0.24680 0.00884 0.99435 0 54.91875 0.87661 45.81039 0.73126 13.55409 0.43491 11.30438 0.36266 55196.441839 0.000472 0.26395 0.00962 1.00000 0 54.95333 0.91570 45.94920 0.76561 14.50488 0.47015 12.13327 0.39327 55196.442814 0.000503 0.24368 0.00867 1.00000 0 56.07260 0.88939 47.07303 0.74658 13.66401 0.43529 11.47387 0.36546 55196.443795 0.000477 0.26771 0.00972 1.00000 0 52.63827 0.88259 44.83915 0.75182 14.09199 0.45396 12.00363 0.38668 55196.444742 0.000469 0.26917 0.00991 1.00000 0 53.80880 0.90862 45.09632 0.76149 14.48386 0.47396 12.15977 0.39776 55196.445688 0.000477 0.25859 0.00935 1.00000 0 55.38731 0.90737 46.57164 0.76290 14.32260 0.46160 12.03424 0.38786 55196.447019 0.000854 0.24367 0.00684 0.99661 0 54.66986 0.67409 46.04316 0.56767 13.32160 0.33619 11.22599 0.28326
