/* ** ** 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 54196.281869 0.000613 0.12838 0.00997 0.98585 0 15.99894 0.40954 14.60003 0.37372 2.05391 0.15065 1.87451 0.13755 54196.283032 0.000550 0.14247 0.01131 0.98421 0 15.84455 0.43151 14.49002 0.39462 2.25731 0.16825 2.06490 0.15398 54196.284210 0.000628 0.12410 0.00966 0.99078 0 15.83434 0.40397 14.60902 0.37271 1.96507 0.14459 1.81288 0.13339 54196.285408 0.000570 0.13808 0.01068 0.98477 0 16.03135 0.42730 14.68350 0.39135 2.21361 0.16072 2.02784 0.14723 54196.286626 0.000648 0.11968 0.00929 0.98661 0 16.01831 0.39804 14.73413 0.36611 1.91702 0.14105 1.76366 0.12977 54196.287867 0.000593 0.13444 0.01036 0.99024 0 15.82174 0.41709 14.49525 0.38212 2.12700 0.15402 1.94781 0.14105 54196.288990 0.000530 0.15672 0.01207 0.98361 0 15.25022 0.43136 14.07384 0.39809 2.39005 0.17125 2.20575 0.15804 54196.290159 0.000634 0.12572 0.00961 0.99087 0 15.80898 0.40109 14.50610 0.36803 1.98749 0.14334 1.82128 0.13136 54196.291464 0.000666 0.12290 0.00917 0.97391 0 16.08058 0.39264 14.79089 0.36112 1.97638 0.13930 1.81636 0.12800 54196.292951 0.000822 0.12928 0.00864 0.98374 0 15.65904 0.35095 14.44793 0.32380 2.02433 0.12749 1.86770 0.11763 54196.348437 0.000512 0.16380 0.01266 0.98305 0 15.08251 0.43635 13.93599 0.40315 2.47053 0.17705 2.28145 0.16352 54196.349553 0.000605 0.12294 0.00943 1.00000 0 16.62327 0.41979 15.40453 0.38901 2.04369 0.14808 1.89130 0.13704 54196.350763 0.000605 0.13236 0.01029 0.99522 0 15.38325 0.40443 14.21911 0.37382 2.03617 0.14891 1.88188 0.13765 54196.351894 0.000527 0.15558 0.01221 0.98901 0 15.14118 0.42995 13.97923 0.39692 2.35566 0.17232 2.17462 0.15906 54196.352974 0.000553 0.14665 0.01133 1.00000 0 15.17041 0.41777 14.10620 0.38846 2.22479 0.16054 2.06872 0.14927 54196.354163 0.000637 0.12181 0.00942 0.98636 0 15.97631 0.39946 14.80874 0.37027 1.94611 0.14233 1.80383 0.13194 54196.355419 0.000619 0.12990 0.01002 0.98598 0 15.47302 0.40011 14.34619 0.37094 2.00998 0.14601 1.86388 0.13541 54196.356556 0.000518 0.15782 0.01224 0.98883 0 15.26936 0.43464 14.14730 0.40267 2.40978 0.17393 2.23235 0.16108 54196.358046 0.000972 0.14133 0.00814 0.98512 0 15.98907 0.32227 14.86709 0.29966 2.25969 0.12190 2.10112 0.11334
