/* ** ** 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 59347.278208 0.000564 0.14130 0.01118 0.99487 0 15.95646 0.44120 14.18219 0.39180 2.25461 0.16708 2.00003 0.14811 59347.279345 0.000573 0.14550 0.01127 0.98990 0 15.70214 0.43163 13.86401 0.38112 2.28473 0.16540 2.01753 0.14608 59347.280558 0.000639 0.13650 0.01046 0.98190 0 15.03970 0.39808 13.40981 0.35490 2.05286 0.14767 1.83062 0.13168 59347.281822 0.000625 0.13233 0.01015 0.99074 0 15.71249 0.41171 13.96212 0.36582 2.07928 0.14996 1.84692 0.13320 59347.283060 0.000613 0.13797 0.01046 0.99528 0 15.57598 0.41518 13.79190 0.36760 2.14901 0.15257 1.89982 0.13488 59347.284235 0.000561 0.13864 0.01079 0.98969 0 16.53339 0.44288 14.71216 0.39409 2.29226 0.16753 2.03971 0.14906 59347.285384 0.000587 0.13823 0.01084 0.99015 0 15.86400 0.43081 14.03820 0.38119 2.19293 0.16132 1.93938 0.14267 59347.287068 0.001097 0.12269 0.00724 0.99472 0 16.39574 0.31817 14.52003 0.28176 2.01153 0.11218 1.77897 0.09920
