/* ** ** 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 54928.864366 0.000420 0.14937 0.01142 0.99310 0 20.72630 0.56768 18.54601 0.50793 3.09596 0.22108 2.77011 0.19782 54928.865188 0.000402 0.14981 0.01154 0.98561 0 21.49760 0.59355 19.27777 0.53226 3.22053 0.23153 2.88784 0.20761 54928.866044 0.000454 0.13908 0.01079 0.99363 0 20.13140 0.54069 18.06134 0.48509 2.79983 0.20382 2.51193 0.18286 54928.866933 0.000434 0.14357 0.01105 0.99333 0 20.64900 0.56074 18.52996 0.50319 2.96456 0.21346 2.66027 0.19155 54928.867798 0.000431 0.14163 0.01084 1.00000 0 20.96395 0.56653 18.80752 0.50826 2.96911 0.21257 2.66371 0.19071 54928.868625 0.000396 0.15276 0.01179 0.99270 0 21.22715 0.59525 19.04364 0.53402 3.24260 0.23312 2.90908 0.20914 54928.869453 0.000431 0.14423 0.01109 1.00000 0 20.51997 0.56037 18.40994 0.50275 2.95959 0.21277 2.65527 0.19089 54928.870283 0.000399 0.15117 0.01166 0.98551 0 21.49011 0.59459 19.27973 0.53343 3.24868 0.23392 2.91456 0.20986 54928.871082 0.000399 0.15732 0.01235 0.98551 0 20.35126 0.58255 18.25545 0.52256 3.20170 0.23405 2.87208 0.20996 54928.871907 0.000425 0.14128 0.01075 1.00000 0 21.59985 0.57941 19.29172 0.51748 3.05156 0.21736 2.72721 0.19426 54928.872731 0.000399 0.15744 0.01242 0.98551 0 20.39309 0.58262 18.21192 0.52027 3.21075 0.23605 2.86831 0.21088 54928.873530 0.000399 0.15204 0.01178 1.00000 0 21.04244 0.59127 18.78595 0.52786 3.19940 0.23097 2.85780 0.20631 54928.874308 0.000379 0.16061 0.01244 1.00000 0 20.96266 0.60362 18.80373 0.54145 3.36688 0.24205 3.02011 0.21712 54928.875200 0.000512 0.14080 0.01001 0.98396 0 21.23170 0.52693 18.90311 0.46912 2.98942 0.19920 2.65981 0.17722 54928.937389 0.000778 0.14965 0.00819 0.98512 0 21.57918 0.42367 19.82674 0.38924 3.22935 0.16506 2.96676 0.15165
