/* ** ** 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 59343.223075 0.000399 0.14312 0.01110 0.98551 0 22.57366 0.61446 20.19927 0.54980 3.23071 0.23452 2.89288 0.21001 59343.223804 0.000330 0.17712 0.01415 0.98246 0 22.00766 0.67119 19.62287 0.59845 3.89811 0.28783 3.48223 0.25716 59343.224490 0.000356 0.16214 0.01250 0.99187 0 22.35340 0.64484 20.17383 0.58196 3.62434 0.25900 3.27093 0.23375 59343.225182 0.000336 0.16840 0.01341 0.99138 0 22.52167 0.67106 20.15092 0.60035 3.79262 0.28007 3.39139 0.25046 59343.225853 0.000336 0.17968 0.01423 1.00000 0 21.23075 0.65300 18.96803 0.58338 3.81483 0.27839 3.41228 0.24901 59343.226513 0.000324 0.17196 0.01368 0.99107 0 22.65473 0.68665 20.42186 0.61897 3.89581 0.28658 3.51185 0.25834 59343.227175 0.000339 0.16972 0.01321 0.99145 0 22.48708 0.66855 20.17389 0.59973 3.81657 0.27459 3.42452 0.24633 59343.227852 0.000339 0.17516 0.01370 1.00000 0 21.37903 0.64809 19.28473 0.58460 3.74476 0.27007 3.37813 0.24362 59343.228561 0.000370 0.15591 0.01226 0.99219 0 22.04501 0.63338 19.89005 0.57147 3.43694 0.25148 3.10096 0.22689 59343.229253 0.000321 0.16625 0.01312 1.00000 0 23.56768 0.70154 21.21965 0.63166 3.91809 0.28630 3.52814 0.25783 59343.229938 0.000365 0.16832 0.01304 0.98413 0 21.28230 0.62766 19.04346 0.56156 3.58214 0.25662 3.20201 0.22941 59343.230636 0.000333 0.17358 0.01357 0.98261 0 22.33168 0.67270 20.14975 0.60697 3.87645 0.27957 3.49771 0.25225 59343.231298 0.000330 0.17290 0.01352 0.99123 0 22.55233 0.68238 20.20741 0.61148 3.89931 0.28124 3.49771 0.25225 59343.231967 0.000339 0.17130 0.01356 1.00000 0 21.87794 0.65827 19.65243 0.59131 3.74778 0.27435 3.36600 0.24629 59343.232661 0.000356 0.16197 0.01252 1.00000 0 22.08637 0.64156 19.92911 0.57890 3.57724 0.25629 3.22805 0.23127 59343.233341 0.000324 0.16786 0.01342 1.00000 0 23.00805 0.68855 20.75425 0.62110 3.86203 0.28632 3.48397 0.25829 59343.234183 0.000518 0.15571 0.01051 0.97765 0 22.60085 0.56216 20.39843 0.50738 3.51918 0.22087 3.17623 0.19934
