/* ** ** 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 57778.464011 0.000275 0.21550 0.01693 1.00000 0 21.52452 0.71231 19.59573 0.64848 4.63846 0.33046 4.22281 0.30085 57778.464625 0.000339 0.16766 0.01304 0.98291 0 22.52683 0.65910 20.50823 0.60004 3.77676 0.27216 3.43833 0.24777 57778.465314 0.000350 0.16249 0.01259 0.99174 0 22.51403 0.64852 20.49657 0.59041 3.65836 0.26323 3.33054 0.23965 57778.465956 0.000292 0.17843 0.01441 1.00000 0 23.58128 0.72749 21.46819 0.66230 4.20768 0.31414 3.83063 0.28599 57778.466564 0.000315 0.17964 0.01406 1.00000 0 22.18090 0.67882 20.19329 0.61799 3.98465 0.28714 3.62759 0.26141 57778.467191 0.000312 0.17322 0.01353 1.00000 0 23.21596 0.69847 21.13560 0.63588 4.02155 0.28980 3.66118 0.26383 57778.467802 0.000298 0.18705 0.01473 0.99029 0 22.77912 0.70914 20.73791 0.64560 4.26080 0.30818 3.87900 0.28056 57778.468433 0.000333 0.17443 0.01327 0.96456 0 23.34287 0.67692 21.25114 0.61627 4.07174 0.28647 3.70688 0.26080 57778.601031 0.000318 0.18650 0.01463 1.00000 0 21.66469 0.67633 19.36007 0.60439 4.04049 0.29073 3.61067 0.25981 57778.601679 0.000330 0.18786 0.01480 1.00000 0 20.76232 0.65139 18.55369 0.58209 3.90040 0.28180 3.48549 0.25182 57778.602318 0.000310 0.18841 0.01478 0.99065 0 22.25488 0.69456 19.88748 0.62068 4.19296 0.30171 3.74692 0.26961 57778.602995 0.000367 0.16270 0.01265 0.99213 0 21.57062 0.62662 19.27601 0.55996 3.50962 0.25319 3.13627 0.22626 57778.603768 0.000405 0.16176 0.01186 0.99849 0 22.24955 0.60846 19.88271 0.54373 3.59918 0.24489 3.21631 0.21884
