/* ** ** 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 60031.080149 0.000365 0.15258 0.01158 0.99206 0 23.32327 0.64673 21.23467 0.58871 3.55875 0.25145 3.23864 0.22882 60031.080847 0.000333 0.15993 0.01251 0.99130 0 23.49822 0.67984 21.57064 0.62407 3.75808 0.27302 3.44980 0.25063 60031.081550 0.000370 0.15193 0.01181 1.00000 0 22.15840 0.62572 20.32608 0.57398 3.36649 0.24393 3.08813 0.22376 60031.082328 0.000408 0.14012 0.01084 0.99291 0 21.96491 0.59556 20.15041 0.54636 3.07771 0.22301 2.82344 0.20458 60031.083121 0.000385 0.14952 0.01172 1.00000 0 21.45608 0.60588 19.68348 0.55582 3.20815 0.23466 2.94308 0.21527 60031.083867 0.000362 0.15651 0.01207 1.00000 0 22.24370 0.63397 20.31072 0.57886 3.48143 0.24954 3.17578 0.22761 60031.084605 0.000370 0.15567 0.01243 0.97656 0 21.61521 0.61315 19.83130 0.56255 3.36481 0.25121 3.08710 0.23047 60031.085337 0.000362 0.15448 0.01197 0.98400 0 22.66334 0.63778 20.79414 0.58517 3.50113 0.25264 3.21240 0.23180 60031.086014 0.000315 0.18103 0.01409 1.00000 0 22.15649 0.67575 20.32893 0.62001 4.01095 0.28719 3.68014 0.26350 60031.086726 0.000396 0.14414 0.01126 0.98540 0 21.92599 0.60136 20.11636 0.55172 3.16039 0.23117 2.89948 0.21208 60031.087479 0.000356 0.15932 0.01237 0.99187 0 22.15992 0.63564 20.32913 0.58312 3.53041 0.25475 3.23873 0.23370 60031.088199 0.000365 0.15181 0.01186 0.97619 0 22.96288 0.64222 21.06924 0.58926 3.48611 0.25431 3.19865 0.23334 60031.088946 0.000382 0.13800 0.01070 1.00000 0 23.66238 0.63583 21.70877 0.58333 3.26529 0.23757 2.99573 0.21796 60031.089704 0.000376 0.15162 0.01185 0.97692 0 22.26953 0.62298 20.43267 0.57159 3.37653 0.24632 3.09790 0.22599 60031.090528 0.000448 0.14462 0.01028 0.99355 0 22.57006 0.57235 20.70333 0.52502 3.26398 0.21680 2.99402 0.19887
