/* ** ** 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 55976.323657 0.000556 0.08846 0.01529 0.96875 0 5.80843 0.28309 4.49310 0.21887 0.51383 0.08521 0.39576 0.06557 55976.324511 0.000298 0.09197 0.02149 0.98058 0 5.39916 0.36605 4.31044 0.29224 0.49658 0.11104 0.39670 0.08870 55976.325168 0.000359 0.08421 0.01790 0.97581 0 5.91604 0.34974 4.72221 0.27917 0.49819 0.10169 0.39736 0.08111 55976.325819 0.000292 0.08108 0.01915 1.00000 0 6.04868 0.39762 4.83186 0.31763 0.49041 0.11126 0.39163 0.08885 55976.326426 0.000315 0.07652 0.01804 0.97248 0 6.26138 0.38600 4.99771 0.30809 0.47912 0.10901 0.38239 0.08701 55976.327167 0.000425 0.08600 0.01694 0.95918 0 5.79504 0.32079 4.60844 0.25508 0.49839 0.09419 0.39783 0.07518 55976.328015 0.000422 0.08483 0.01670 0.96575 0 5.90845 0.32496 4.68175 0.25745 0.50122 0.09473 0.39783 0.07518 55976.328730 0.000292 0.07735 0.01797 1.00000 0 6.47297 0.40720 5.13942 0.32330 0.50070 0.11197 0.39670 0.08870 55976.329334 0.000312 0.07799 0.01810 0.95370 0 6.30085 0.39143 4.97441 0.30902 0.49140 0.10989 0.38900 0.08698 55976.329956 0.000310 0.09322 0.02240 0.95327 0 5.14987 0.35394 4.10566 0.28217 0.48008 0.11053 0.38277 0.08812 55976.330853 0.000587 0.08460 0.01411 0.96552 0 5.90984 0.27582 4.70625 0.21964 0.49997 0.08006 0.39862 0.06383 55976.331794 0.000353 0.07559 0.01803 0.97541 0 5.42475 0.33764 4.33668 0.26992 0.41004 0.09440 0.32809 0.07553 55976.332442 0.000295 0.08953 0.02092 1.00000 0 5.48474 0.37172 4.38727 0.29734 0.49106 0.10981 0.39281 0.08784 55976.333050 0.000312 0.08141 0.01922 1.00000 0 5.65315 0.36900 4.50161 0.29383 0.46023 0.10442 0.36625 0.08309 55976.333660 0.000298 0.08344 0.01943 0.98058 0 6.02166 0.38980 4.75996 0.30809 0.50247 0.11237 0.39670 0.08870 55976.334687 0.000729 0.08471 0.01250 0.98413 0 6.08342 0.24875 4.86065 0.19875 0.51535 0.07308 0.41179 0.05840
