/* ** ** 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 59367.190438 0.000616 0.13106 0.01034 0.98122 0 15.48616 0.40605 14.12243 0.37021 2.02956 0.15104 1.84973 0.13763 59367.191694 0.000639 0.12721 0.00961 0.96833 0 15.97949 0.40568 14.66542 0.37230 2.03272 0.14465 1.86406 0.13264 59367.192976 0.000642 0.13158 0.01022 0.98649 0 14.96176 0.39547 13.66957 0.36132 1.96870 0.14383 1.79963 0.13149 59367.194229 0.000611 0.13748 0.01042 0.97630 0 15.48254 0.40840 14.22506 0.37524 2.12851 0.15126 1.95708 0.13908 59367.195464 0.000625 0.12501 0.00968 0.99537 0 15.82123 0.40810 14.58012 0.37608 1.97777 0.14436 1.82266 0.13304 59367.196636 0.000547 0.15295 0.01172 0.98413 0 15.22126 0.43256 14.01783 0.39836 2.32809 0.16566 2.14467 0.15261 59367.197782 0.000599 0.13644 0.01056 0.98068 0 15.49654 0.41880 14.20026 0.38380 2.11437 0.15340 1.93907 0.14064 59367.199052 0.000671 0.12734 0.00969 0.96983 0 15.13647 0.39007 13.86996 0.35739 1.92744 0.13806 1.76511 0.12640 59367.200554 0.000830 0.12403 0.00856 0.98606 0 15.36089 0.35081 14.08858 0.32178 1.90527 0.12405 1.74746 0.11379
