/* ** ** 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 58927.955675 0.000229 0.15648 0.01199 1.00000 0 36.88459 1.04257 32.26092 0.91176 5.77182 0.41086 5.04887 0.35935 58927.956127 0.000223 0.16464 0.01282 1.00000 0 35.17174 1.03592 31.17769 0.91829 5.79055 0.41758 5.13313 0.37017 58927.956558 0.000208 0.18445 0.01439 0.98611 0 34.23906 1.05694 30.31760 0.93589 6.31535 0.45246 5.59234 0.40065 58927.957001 0.000234 0.15794 0.01198 1.00000 0 36.03091 1.02093 31.65484 0.89694 5.69056 0.40040 4.99595 0.35151 58927.957432 0.000197 0.17408 0.01354 1.00000 0 38.26008 1.14887 33.76323 1.01386 6.66047 0.47781 5.87144 0.42123 58927.957843 0.000214 0.16442 0.01266 1.00000 0 37.72281 1.09915 32.96950 0.96064 6.20236 0.44207 5.41977 0.38631 58927.958291 0.000234 0.15440 0.01218 0.98765 0 36.42492 1.03808 31.54453 0.89899 5.62384 0.41380 4.87296 0.35843 58927.958780 0.000255 0.17937 0.01275 0.98983 0 35.34435 0.98541 30.79724 0.85844 6.33969 0.41463 5.52887 0.36164
