/* ** ** 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 59157.476168 0.000122 0.20083 0.01584 1.00000 0 65.32464 2.09765 47.38407 1.52136 13.11924 0.94541 9.51120 0.68499 59157.476848 0.000558 0.23921 0.00866 1.00000 0 67.53647 1.06881 42.52736 0.67280 16.15520 0.52594 10.17460 0.33115 59157.477800 0.000394 0.23235 0.01022 1.00000 0 67.61850 1.28116 42.03764 0.79646 15.71136 0.62359 9.76201 0.38743 59157.478752 0.000558 0.24996 0.00903 1.00000 0 65.50213 1.05822 40.88299 0.66049 16.37314 0.52897 10.22023 0.33020 59157.479435 0.000124 0.22899 0.01779 0.97674 0 68.86330 2.31469 43.17701 1.45124 15.76897 1.10442 9.88318 0.69223 59157.479689 0.000130 0.23796 0.01892 1.00000 0 60.82555 2.15291 37.25328 1.31858 14.47417 1.03023 8.86367 0.63086 59157.479944 0.000124 0.23497 0.01867 1.00000 0 64.47709 2.26243 39.69502 1.39285 15.15015 1.07986 9.32721 0.66480 59157.480190 0.000122 0.23048 0.01856 1.00000 0 66.94854 2.33273 41.30332 1.43915 15.43059 1.11988 9.52081 0.69097 59157.480482 0.000171 0.24148 0.01606 1.00000 0 65.16347 1.91997 40.70950 1.19947 15.73535 0.93834 9.83004 0.58619 59157.481203 0.000550 0.24754 0.00904 1.00000 0 67.10276 1.08393 41.56479 0.67137 16.61073 0.54423 10.28785 0.33705 59157.482242 0.000489 0.23409 0.00933 0.99408 0 66.43617 1.14289 41.44802 0.71298 15.55176 0.55936 9.70088 0.34893 59157.482855 0.000124 0.22881 0.01784 1.00000 0 69.22385 2.34484 42.60943 1.44323 15.83893 1.11211 9.75590 0.68509 59157.483110 0.000130 0.24217 0.01860 1.00000 0 65.94829 2.26319 40.15837 1.37813 15.97098 1.09743 9.72297 0.66813 59157.483642 0.000402 0.23579 0.01022 0.99507 0 67.17678 1.26913 41.73332 0.78841 15.83943 0.61825 9.84052 0.38412 59157.883289 0.000414 0.25520 0.00918 1.00000 0 60.14306 0.98205 54.48083 0.88952 15.34832 0.49187 13.90356 0.44553 59157.884105 0.000402 0.26327 0.00963 1.00000 0 59.00266 0.98317 53.78112 0.89616 15.53358 0.50600 14.15868 0.46122 59157.884915 0.000408 0.25773 0.00940 1.00000 0 59.45234 0.97793 54.15814 0.89084 15.32239 0.49912 13.95785 0.45467 59157.885722 0.000399 0.27164 0.00997 0.99275 0 58.07203 0.97798 52.90923 0.89103 15.77497 0.51468 14.37254 0.46893 59157.886865 0.000744 0.26332 0.00711 0.99611 0 58.96037 0.72366 53.72522 0.65941 15.52537 0.37347 14.14684 0.34031
