/* ** ** 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 57386.500843 0.000521 0.22571 0.00803 1.00000 0 53.09213 0.80650 49.04070 0.74495 11.98337 0.38537 11.06763 0.35594 57386.501850 0.000486 0.23511 0.00843 0.99405 0 54.64287 0.85175 50.37472 0.78520 12.84700 0.41475 11.84521 0.38233 57386.502839 0.000503 0.23199 0.00824 0.99425 0 53.45397 0.82397 49.64103 0.76518 12.40073 0.39699 11.52439 0.36894 57386.503823 0.000480 0.23859 0.00850 1.00000 0 53.98159 0.84752 50.30228 0.78975 12.87921 0.41189 12.00139 0.38382 57386.504810 0.000506 0.23002 0.00817 1.00000 0 53.46817 0.82234 49.47976 0.76098 12.29871 0.39396 11.38124 0.36454 57386.505817 0.000501 0.22819 0.00815 1.00000 0 53.92222 0.82998 50.26109 0.77362 12.30457 0.39654 11.46914 0.36962 57386.506792 0.000475 0.24115 0.00866 1.00000 0 53.94836 0.85535 50.08339 0.79407 13.00958 0.41906 12.07725 0.38902 57386.507776 0.000509 0.22161 0.00800 1.00000 0 54.48468 0.83151 50.42355 0.76948 12.07416 0.39471 11.17347 0.36528 57386.508771 0.000486 0.24106 0.00858 1.00000 0 52.94843 0.83451 49.16346 0.77484 12.76398 0.40716 11.85273 0.37809 57386.509778 0.000521 0.22729 0.00815 1.00000 0 51.85558 0.79714 48.32659 0.74289 11.78615 0.38159 10.98400 0.35562 57386.511037 0.000738 0.22887 0.00674 1.00000 0 54.02633 0.68888 49.84137 0.63551 12.36500 0.32850 11.41239 0.30321
