/* ** ** 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 59726.908066 0.000203 0.21487 0.01708 1.00000 0 28.53345 0.95388 26.24263 0.87718 6.13084 0.44216 5.64090 0.40685 59726.908486 0.000217 0.19583 0.01519 1.00000 0 29.85898 0.94310 27.47160 0.86768 5.84727 0.41439 5.38367 0.38156 59726.908926 0.000223 0.19995 0.01579 0.98701 0 28.00626 0.89984 25.98695 0.83496 5.59988 0.40389 5.19557 0.37473 59726.909383 0.000234 0.18510 0.01431 0.98765 0 29.23506 0.89276 27.13220 0.82854 5.41138 0.38449 5.02215 0.35683 59726.909863 0.000246 0.17643 0.01355 1.00000 0 28.97305 0.87050 26.88789 0.80785 5.11166 0.36142 4.74380 0.33541 59726.910346 0.000237 0.18361 0.01407 0.98780 0 29.31971 0.89146 27.20914 0.82729 5.38352 0.37878 4.99597 0.35152 59726.910818 0.000234 0.18149 0.01418 1.00000 0 29.35086 0.89671 27.17105 0.83007 5.32691 0.38313 4.93114 0.35465 59726.911284 0.000231 0.20142 0.01596 1.00000 0 26.56115 0.86284 24.53227 0.79684 5.34984 0.38680 4.94269 0.35734 59726.911750 0.000234 0.18465 0.01443 0.98765 0 29.13731 0.89183 27.03894 0.82761 5.38023 0.38695 4.99278 0.35909 59726.912262 0.000278 0.14854 0.01165 1.00000 0 29.50937 0.82828 27.38490 0.76864 4.38339 0.32092 4.06781 0.29782 59726.912774 0.000234 0.18419 0.01434 0.98765 0 29.31490 0.89753 27.20558 0.83295 5.39940 0.38643 5.01091 0.35863 59726.913240 0.000231 0.18643 0.01433 1.00000 0 29.23758 0.90318 27.13284 0.83816 5.45082 0.38352 5.05842 0.35591 59726.913712 0.000240 0.17680 0.01396 1.00000 0 28.78385 0.87646 26.71053 0.81333 5.08896 0.37072 4.72242 0.34402 59726.914198 0.000246 0.17336 0.01342 1.00000 0 29.08822 0.87126 26.99399 0.80854 5.04265 0.36011 4.67959 0.33418 59726.914684 0.000240 0.18044 0.01412 0.98795 0 29.18440 0.88739 26.87732 0.81720 5.26613 0.37974 4.84657 0.34948 59726.915141 0.000217 0.19906 0.01547 0.98667 0 29.35774 0.93412 27.23820 0.86667 5.84382 0.41422 5.42188 0.38431 59726.915566 0.000208 0.21015 0.01655 1.00000 0 28.79651 0.95770 26.49469 0.88114 6.05152 0.43209 5.56001 0.39699 59726.915995 0.000220 0.19967 0.01561 0.97368 0 29.00974 0.92168 26.92108 0.85532 5.79224 0.41364 5.37520 0.38386 59726.916443 0.000229 0.18243 0.01418 1.00000 0 29.93353 0.92066 27.77738 0.85434 5.46069 0.38990 5.06735 0.36182 59726.916909 0.000237 0.18706 0.01477 1.00000 0 27.63831 0.86392 25.64845 0.80172 5.16994 0.37475 4.79771 0.34776 59726.917366 0.000220 0.19326 0.01507 1.00000 0 29.33533 0.92907 27.21765 0.86201 5.66937 0.40384 5.26011 0.37469 59726.917815 0.000229 0.19284 0.01505 1.00000 0 28.31520 0.89329 26.27800 0.82902 5.46020 0.38987 5.06735 0.36182
