/* ** ** 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 58252.946829 0.000350 0.19634 0.01541 0.99174 0 18.51388 0.58914 16.82196 0.53521 3.63496 0.26079 3.30349 0.23698 58252.947590 0.000411 0.17096 0.01328 0.99296 0 18.10013 0.53835 16.44925 0.48920 3.09439 0.22200 2.81148 0.20168 58252.948395 0.000394 0.17406 0.01382 0.99265 0 18.41936 0.55583 16.68627 0.50345 3.20606 0.23548 2.90317 0.21324 58252.949144 0.000356 0.20194 0.01612 0.99187 0 17.77528 0.57641 15.94429 0.51706 3.58955 0.26183 3.21932 0.23482 58252.949882 0.000382 0.18381 0.01457 0.96212 0 18.49817 0.56515 16.76310 0.51213 3.40011 0.24870 3.07680 0.22502 58252.950663 0.000399 0.17640 0.01365 0.98551 0 18.52922 0.55258 16.70513 0.49814 3.26857 0.23332 2.94430 0.21013 58252.951517 0.000454 0.15089 0.01166 0.99363 0 18.41732 0.51328 16.78037 0.46763 2.77894 0.20032 2.53207 0.18252 58252.952411 0.000440 0.15565 0.01185 1.00000 0 18.66595 0.52731 16.94028 0.47854 2.90543 0.20546 2.63597 0.18639 58252.953270 0.000420 0.17044 0.01349 0.98621 0 17.74213 0.52827 16.04275 0.47759 3.02388 0.22168 2.73665 0.20058 58252.954167 0.000477 0.14985 0.01148 0.98182 0 18.02576 0.49872 16.39062 0.45345 2.70120 0.19287 2.45577 0.17532 58252.955085 0.000440 0.15731 0.01235 1.00000 0 18.05907 0.51725 16.47204 0.47178 2.84093 0.20766 2.58779 0.18917 58252.955903 0.000379 0.17354 0.01374 1.00000 0 18.78481 0.56796 17.18670 0.51962 3.25998 0.23844 2.98285 0.21815 58252.956676 0.000394 0.17342 0.01360 1.00000 0 18.32884 0.55084 16.68115 0.50126 3.17854 0.23025 2.89402 0.20962 58252.957697 0.000628 0.16444 0.01068 0.99078 0 17.55340 0.42445 16.10504 0.38943 2.88651 0.17405 2.64948 0.15977
