/* ** ** 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 54559.917573 0.000446 0.26427 0.00956 1.00000 0 60.28000 1.00010 48.81000 0.80726 15.93048 0.51225 12.90637 0.41426 54559.918476 0.000457 0.24001 0.00871 1.00000 0 60.71240 0.96699 51.85413 0.82579 14.57172 0.47532 12.45456 0.40617 54559.919375 0.000443 0.24718 0.00886 1.00000 0 60.97746 0.97535 52.55460 0.84062 15.07253 0.48379 12.99073 0.41697 54559.920232 0.000414 0.26143 0.00949 1.00000 0 61.66512 1.01616 53.11692 0.87529 16.12137 0.52143 13.88643 0.44914 54559.921065 0.000420 0.26017 0.00947 1.00000 0 60.71824 1.00258 52.31752 0.86386 15.79719 0.51254 13.61200 0.44165 54559.921913 0.000428 0.25650 0.00928 1.00000 0 60.62775 0.99258 52.25241 0.85546 15.55116 0.50146 13.40315 0.43219 54559.922793 0.000451 0.24470 0.00878 0.98713 0 61.24259 0.97596 52.77819 0.84108 14.98594 0.48175 12.91387 0.41514 54559.923664 0.000420 0.24943 0.00903 1.00000 0 63.95582 1.03272 54.66866 0.88259 15.95235 0.51719 13.63963 0.44208 54559.924483 0.000399 0.26737 0.00963 0.98552 0 64.01392 1.05947 55.23853 0.91423 17.11531 0.54738 14.76933 0.47235 54559.925310 0.000428 0.25373 0.00931 0.98652 0 61.42943 1.00515 53.12415 0.86925 15.58630 0.51188 13.47907 0.44269 54559.926158 0.000420 0.25140 0.00916 0.98624 0 63.42315 1.03388 54.79052 0.89315 15.94454 0.51972 13.77457 0.44898 54559.926983 0.000405 0.25660 0.00947 1.00000 0 63.06267 1.04055 54.47459 0.89884 16.18187 0.53398 13.97878 0.46127 54559.927784 0.000396 0.26453 0.00971 1.00000 0 62.69090 1.04128 54.24271 0.90096 16.58380 0.54304 14.34970 0.46988 54559.928588 0.000408 0.25782 0.00946 1.00000 0 62.66075 1.03226 54.10598 0.89133 16.15502 0.52981 13.95004 0.45748 54559.929769 0.000773 0.25084 0.00668 0.99625 0 64.18736 0.75794 55.51552 0.65554 16.10108 0.38430 13.92629 0.33240
