/* ** ** 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 55245.022353 0.000258 0.30998 0.01135 1.00000 0 79.01353 1.40941 72.73473 1.29734 24.49228 0.78364 22.54823 0.72138 55245.022885 0.000275 0.27686 0.01024 1.00000 0 81.47585 1.38811 74.57059 1.27040 22.55730 0.74067 20.64458 0.67787 55245.023409 0.000249 0.30996 0.01144 1.00000 0 81.83759 1.46739 74.57081 1.33705 25.36620 0.81815 23.12665 0.74593 55245.023909 0.000252 0.31600 0.01159 1.00000 0 81.38597 1.46106 73.29379 1.31565 25.71772 0.82253 23.17095 0.74089 55245.024430 0.000269 0.28169 0.01043 1.00000 0 81.36141 1.40181 74.82266 1.28915 22.91903 0.75144 21.07708 0.69105 55245.024971 0.000272 0.28075 0.01044 1.00000 0 80.61538 1.39076 74.12861 1.27886 22.63257 0.74544 20.81161 0.68546 55245.025507 0.000263 0.29012 0.01065 1.00000 0 81.72386 1.41928 75.14839 1.30509 23.70932 0.76706 21.80163 0.70534 55245.026033 0.000263 0.29714 0.01090 1.00000 0 80.14487 1.40570 73.70154 1.29269 23.81450 0.76732 21.89999 0.70563 55245.026577 0.000281 0.26831 0.00981 1.00000 0 82.25919 1.37300 75.65347 1.26274 22.07103 0.71813 20.29885 0.66047 55245.027124 0.000266 0.28552 0.01048 1.00000 0 82.05296 1.41997 75.45103 1.30572 23.42759 0.75834 21.54288 0.69734 55245.027654 0.000263 0.29043 0.01064 1.00000 0 81.97971 1.42010 75.36954 1.30560 23.80975 0.76871 21.88969 0.70671 55245.028186 0.000269 0.29421 0.01076 1.00000 0 79.40940 1.38680 73.01672 1.27516 23.36315 0.75049 21.48218 0.69007 55245.028785 0.000330 0.30214 0.00985 0.99702 0 80.78696 1.26500 74.28754 1.16323 24.40932 0.69750 22.44545 0.64138
