/* ** ** 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 55572.466613 0.000576 0.14509 0.02260 0.96985 0 8.38091 0.45557 3.62472 0.19487 1.21597 0.17753 0.51092 0.07355 55572.467522 0.000333 0.09607 0.02284 0.96522 0 9.96864 0.70070 3.69343 0.25948 0.95770 0.21754 0.35628 0.08085 55572.468196 0.000341 0.08799 0.02117 0.98305 0 10.23182 0.70178 3.84978 0.26376 0.90031 0.20767 0.33644 0.07749 55572.468893 0.000356 0.11702 0.02765 0.94309 0 8.08215 0.61768 2.94809 0.22531 0.94578 0.21149 0.34540 0.07723 55572.469735 0.000486 0.10477 0.02004 0.95833 0 9.83329 0.57620 3.71900 0.21769 1.03020 0.18756 0.38850 0.07061 55572.470626 0.000405 0.09317 0.02177 0.95000 0 8.90814 0.60448 3.23133 0.21927 0.82997 0.18559 0.30125 0.06736 55572.471466 0.000434 0.06887 0.01594 0.98667 0 10.81339 0.64723 3.93498 0.23552 0.74474 0.16654 0.27072 0.06054 55572.472212 0.000312 0.11170 0.02631 0.93519 0 9.63917 0.71330 3.55157 0.26281 1.07671 0.24076 0.39670 0.08870 55572.472828 0.000304 0.09771 0.02328 0.99048 0 10.70854 0.77738 3.90350 0.28337 1.04630 0.23748 0.38026 0.08629 55572.473488 0.000356 0.08889 0.02080 0.98374 0 9.79533 0.67214 3.70670 0.25421 0.87071 0.19479 0.33113 0.07404 55572.474301 0.000457 0.06921 0.01649 0.94937 0 10.03259 0.61040 3.73259 0.22703 0.69434 0.15999 0.26018 0.05993 55572.475517 0.000758 0.10810 0.01650 0.93511 0 9.60209 0.45500 3.69535 0.17498 1.03796 0.15060 0.40036 0.05797 55572.476648 0.000373 0.09421 0.02303 0.92248 0 9.19353 0.64006 3.44596 0.23989 0.86612 0.20291 0.32360 0.07567 55572.477556 0.000535 0.14834 0.02260 0.94054 0 10.32904 0.56371 3.85576 0.21035 1.53224 0.21798 0.57268 0.08147 55572.478407 0.000315 0.11336 0.02618 0.97248 0 9.38966 0.70895 3.51150 0.26516 1.06443 0.23235 0.39689 0.08661 55572.479295 0.000567 0.10411 0.01895 0.94898 0 9.55530 0.52410 3.57932 0.19615 0.99482 0.17262 0.36859 0.06390
