/* ** ** 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 59664.036051 0.000382 0.10012 0.01490 0.98485 0 8.53921 0.38394 7.76902 0.34931 0.85493 0.12130 0.77779 0.11035 59664.036740 0.000307 0.11776 0.01769 1.00000 0 8.90785 0.43885 8.10018 0.39906 1.04900 0.14883 0.95389 0.13534 59664.037466 0.000420 0.08477 0.01253 0.97241 0 9.29512 0.38403 8.45961 0.34951 0.78795 0.11179 0.71711 0.10174 59664.038204 0.000318 0.11954 0.01841 0.98182 0 8.38236 0.42850 7.57686 0.38738 1.00200 0.14556 0.90788 0.13189 59664.038896 0.000373 0.10038 0.01509 0.99225 0 8.53044 0.38756 7.71897 0.35069 0.85625 0.12272 0.77429 0.11098 59664.039616 0.000347 0.11469 0.01761 0.99167 0 7.89914 0.39202 7.18411 0.35653 0.90591 0.13161 0.82396 0.11970 59664.040316 0.000353 0.09877 0.01523 0.98361 0 8.99705 0.41071 8.18255 0.37353 0.88862 0.13086 0.80828 0.11903 59664.041019 0.000350 0.09095 0.01344 0.98347 0 10.17806 0.43662 9.25533 0.39704 0.92566 0.13091 0.84174 0.11904 59664.041740 0.000370 0.11596 0.01561 0.99219 0 9.34588 0.40863 8.49811 0.37157 1.08377 0.13800 0.98545 0.12548 59664.042426 0.000315 0.11149 0.01661 0.96330 0 9.41021 0.44081 8.55691 0.40084 1.04910 0.14837 0.95397 0.13491 59664.043100 0.000359 0.09876 0.01506 0.99194 0 8.96024 0.40449 8.14969 0.36790 0.88489 0.12893 0.80485 0.11726 59664.043838 0.000379 0.09942 0.01473 0.96947 0 8.72048 0.38614 7.93370 0.35130 0.86696 0.12261 0.78871 0.11154 59664.044654 0.000437 0.08686 0.01281 0.98675 0 8.51169 0.35773 7.73991 0.32529 0.73930 0.10455 0.67226 0.09507 59664.045432 0.000341 0.10893 0.01642 0.96610 0 8.83486 0.41340 7.99854 0.37421 0.96241 0.13793 0.86938 0.12461 59664.046474 0.000700 0.09511 0.01047 0.98760 0 8.90999 0.28832 8.10311 0.26221 0.84746 0.08915 0.77069 0.08108
