/* ** ** 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 54978.444940 0.000266 0.18355 0.01420 1.00000 0 25.80810 0.78583 23.75657 0.72335 4.73706 0.33694 4.36467 0.31042 54978.445434 0.000229 0.19845 0.01548 1.00000 0 27.87476 0.89413 25.42346 0.81540 5.53178 0.39327 5.05196 0.35917 54978.445892 0.000229 0.20146 0.01557 1.00000 0 27.67334 0.88407 25.41520 0.81189 5.57520 0.39230 5.12245 0.36041 54978.446328 0.000208 0.22275 0.01798 1.00000 0 26.89940 0.92267 24.55651 0.84229 5.99191 0.43790 5.46861 0.39960 54978.446812 0.000275 0.17194 0.01357 1.00000 0 26.32077 0.78751 24.10829 0.72118 4.52571 0.33064 4.14463 0.30285 54978.447330 0.000243 0.19154 0.01499 1.00000 0 27.25299 0.85553 24.72894 0.77623 5.22013 0.37419 4.73791 0.33965 54978.447824 0.000252 0.18477 0.01428 1.00000 0 27.16766 0.83378 24.98957 0.76691 5.01978 0.35599 4.61044 0.32696 54978.448299 0.000223 0.21061 0.01639 1.00000 0 27.35854 0.89892 24.81562 0.81531 5.76199 0.40644 5.22949 0.36886 54978.448776 0.000255 0.18053 0.01385 1.00000 0 28.29614 0.85353 25.49813 0.76913 5.10822 0.36045 4.60358 0.32484 54978.449309 0.000278 0.16431 0.01264 1.00000 0 27.60625 0.79964 25.33781 0.73392 4.53597 0.32340 4.16194 0.29675 54978.449806 0.000220 0.19920 0.01561 1.00000 0 28.96606 0.92975 26.25659 0.84277 5.77010 0.41251 5.23083 0.37391 54978.450275 0.000249 0.20186 0.01574 0.98837 0 25.79589 0.82424 23.40846 0.74794 5.20719 0.37038 4.72412 0.33598 54978.450773 0.000249 0.18917 0.01465 1.00000 0 27.15744 0.84335 24.63683 0.76504 5.13742 0.36436 4.66405 0.33076 54978.451256 0.000234 0.19888 0.01551 1.00000 0 27.06547 0.86661 24.77132 0.79311 5.38276 0.38269 4.92722 0.35030 54978.451745 0.000255 0.19060 0.01488 0.97727 0 26.73820 0.82310 24.42875 0.75197 5.09634 0.36556 4.65615 0.33388 54978.452257 0.000258 0.18173 0.01397 0.98876 0 27.59802 0.82992 25.39552 0.76365 5.01534 0.35495 4.60860 0.32612 54978.452772 0.000258 0.17650 0.01381 1.00000 0 27.57763 0.83783 25.22303 0.76626 4.86751 0.35097 4.45418 0.32105 54978.453282 0.000252 0.18109 0.01401 1.00000 0 27.34281 0.83541 25.33623 0.77410 4.95155 0.35203 4.58742 0.32614 54978.453794 0.000260 0.18462 0.01468 0.98889 0 25.97974 0.80137 23.84469 0.73549 4.79633 0.35142 4.40153 0.32249 54978.454280 0.000226 0.21248 0.01689 0.98718 0 26.10536 0.86421 24.09735 0.79771 5.54695 0.40094 5.12233 0.37017 54978.454760 0.000255 0.18728 0.01468 1.00000 0 26.22698 0.81894 24.14929 0.75405 4.91169 0.35310 4.52757 0.32550 54978.455269 0.000255 0.17871 0.01380 1.00000 0 27.64908 0.83202 25.55707 0.76905 4.94128 0.35141 4.56307 0.32453 54978.455750 0.000226 0.20650 0.01640 0.98718 0 27.49609 0.89167 24.95901 0.80932 5.67783 0.41162 5.15981 0.37401 54978.456236 0.000260 0.17384 0.01343 1.00000 0 28.12572 0.83607 25.72289 0.76461 4.88930 0.34868 4.46657 0.31857 54978.456748 0.000252 0.18961 0.01500 0.98851 0 26.16775 0.81914 24.09135 0.75414 4.96161 0.36058 4.56811 0.33193 54978.457257 0.000258 0.17813 0.01376 0.98876 0 27.63057 0.83389 25.43062 0.76746 4.92183 0.34992 4.53529 0.32244 54978.457917 0.000402 0.21296 0.01236 1.00000 0 26.84615 0.65432 24.77669 0.60386 5.71704 0.30115 5.27326 0.27777
