/* ** ** 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 57156.201254 0.000249 0.21112 0.01633 1.00000 0 24.99248 0.81277 22.33918 0.72639 5.27644 0.37035 4.72880 0.33190 57156.201812 0.000310 0.15864 0.01228 0.99065 0 26.10814 0.74271 23.52326 0.66915 4.14170 0.29816 3.72939 0.26847 57156.202426 0.000304 0.16113 0.01233 1.00000 0 26.34446 0.75381 23.76367 0.67993 4.24487 0.30133 3.82855 0.27177 57156.203002 0.000272 0.18832 0.01461 1.00000 0 25.05672 0.77715 22.74716 0.70552 4.71858 0.33558 4.28365 0.30465 57156.203566 0.000292 0.16924 0.01305 0.98020 0 26.38219 0.77191 23.71248 0.69376 4.46497 0.31863 4.02011 0.28681 57156.204121 0.000263 0.19358 0.01489 0.98901 0 26.31974 0.81838 23.36445 0.72650 5.09503 0.35832 4.52603 0.31827 57156.204654 0.000269 0.17964 0.01403 1.00000 0 26.24042 0.79818 23.82196 0.72462 4.71388 0.33910 4.27940 0.30784 57156.205204 0.000281 0.19188 0.01489 1.00000 0 23.79348 0.74672 21.59801 0.67782 4.56557 0.32408 4.14431 0.29418 57156.205788 0.000304 0.16907 0.01291 1.00000 0 25.15170 0.73602 22.83252 0.66816 4.25252 0.29978 3.86037 0.27214 57156.206393 0.000301 0.16447 0.01274 1.00000 0 25.67410 0.74766 23.23577 0.67663 4.22251 0.30320 3.82037 0.27431 57156.207053 0.000359 0.13821 0.01061 0.99194 0 25.72182 0.68387 23.25800 0.61835 3.55504 0.25595 3.21395 0.23136 57156.207715 0.000304 0.16767 0.01289 0.98095 0 25.60628 0.74419 23.16638 0.67326 4.29345 0.30554 3.88344 0.27636 57156.208300 0.000281 0.17050 0.01323 0.98969 0 26.90298 0.79205 24.26242 0.71428 4.58694 0.32933 4.13874 0.29717 57156.208887 0.000307 0.16232 0.01270 1.00000 0 25.29402 0.73700 22.83128 0.66521 4.10576 0.29822 3.70415 0.26906 57156.209512 0.000318 0.16201 0.01232 0.99091 0 25.41889 0.72384 22.94922 0.65350 4.11799 0.29034 3.71871 0.26215 57156.210131 0.000301 0.16686 0.01273 1.00000 0 25.55660 0.74405 23.20340 0.67554 4.26446 0.30079 3.87183 0.27310 57156.210719 0.000286 0.17977 0.01385 1.00000 0 25.15733 0.76199 22.57468 0.68376 4.52257 0.32047 4.05386 0.28721 57156.211352 0.000347 0.13958 0.01077 1.00000 0 26.02656 0.70014 23.50666 0.63232 3.63277 0.26274 3.28314 0.23741 57156.212079 0.000379 0.16648 0.01150 0.99237 0 25.61504 0.66603 23.12020 0.60109 4.26443 0.27293 3.84734 0.24619
