/* ** ** 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 59284.067861 0.000483 0.16154 0.01237 0.97605 0 23.89287 0.67888 15.20652 0.43159 3.85964 0.27446 2.45703 0.17450 59284.068824 0.000480 0.16188 0.01255 0.98795 0 23.50924 0.67764 14.86633 0.42847 3.80569 0.27390 2.40994 0.17339 59284.069788 0.000483 0.15521 0.01200 0.98204 0 24.02784 0.67728 15.52088 0.43742 3.72936 0.26837 2.40994 0.17339 59284.070691 0.000414 0.18797 0.01461 0.99301 0 23.04791 0.71515 14.94159 0.46358 4.33228 0.30878 2.81273 0.20045 59284.071620 0.000515 0.15115 0.01157 0.96629 0 23.71614 0.65144 15.34147 0.42131 3.58479 0.25617 2.31049 0.16508 59284.072548 0.000414 0.17930 0.01397 0.99301 0 24.05455 0.73154 15.60249 0.47441 4.31309 0.30930 2.79097 0.20010 59284.073422 0.000460 0.16764 0.01333 0.98113 0 23.00700 0.67839 14.88883 0.43896 3.85685 0.28492 2.49648 0.18437 59284.074788 0.000906 0.17005 0.00941 0.97701 0 22.92776 0.48232 14.89170 0.31323 3.89877 0.19946 2.53057 0.12945
