/* ** ** 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 57761.454900 0.000243 0.28798 0.01644 0.98810 0 39.55904 1.06255 34.13472 0.91682 11.39236 0.57387 9.82201 0.49479 57761.455672 0.000530 0.30307 0.01108 1.00000 0 41.59663 0.73402 35.99622 0.63520 12.60649 0.40366 10.90907 0.34930 57761.456752 0.000550 0.29473 0.01082 1.00000 0 41.02864 0.71825 35.28277 0.61762 12.09233 0.39000 10.39364 0.33520 57761.457860 0.000558 0.28748 0.01055 1.00000 0 41.09370 0.71011 35.57297 0.61471 11.81370 0.38236 10.22656 0.33099 57761.458549 0.000130 0.26941 0.02061 1.00000 0 42.22853 1.50257 36.55785 1.30079 11.37678 0.77061 9.84899 0.66712 57761.459208 0.000530 0.31760 0.01176 0.99709 0 39.36919 0.71369 34.08096 0.61783 12.50348 0.40356 10.82397 0.34935 57761.521434 0.000124 0.26287 0.02161 1.00000 0 42.72520 1.59377 34.79943 1.29745 11.23104 0.82295 9.15816 0.67015 57761.521680 0.000122 0.28042 0.02223 1.00000 0 40.79565 1.54737 35.41104 1.34323 11.44004 0.79641 9.92581 0.69092 57761.521923 0.000122 0.25189 0.02047 1.00000 0 43.24812 1.58086 37.79126 1.38139 10.89370 0.79084 9.51931 0.69106 57761.522164 0.000119 0.26211 0.02129 1.00000 0 43.19915 1.60243 36.99493 1.37225 11.32307 0.81803 9.69329 0.70006 57761.522407 0.000124 0.26139 0.02142 1.00000 0 40.72208 1.52487 34.96986 1.30959 10.64453 0.77572 9.15371 0.66720 57761.522681 0.000150 0.26778 0.01899 1.00000 0 43.27526 1.43439 36.87008 1.22208 11.58833 0.72657 9.86623 0.61859 57761.523399 0.000567 0.27515 0.01012 1.00000 0 43.40188 0.73644 36.45243 0.61846 11.94211 0.38979 10.03182 0.32744 57761.524099 0.000133 0.23399 0.01884 1.00000 0 43.47028 1.52917 36.72573 1.29194 10.17159 0.73651 8.59612 0.62244 57761.524831 0.000599 0.29323 0.01006 1.00000 0 44.13022 0.71980 37.27753 0.60802 12.94049 0.39081 10.93519 0.33024
