/* ** ** 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 56302.959802 0.000411 0.07597 0.01115 1.00000 0 10.60427 0.41718 9.26645 0.36454 0.80559 0.11393 0.70540 0.09976 56302.960534 0.000321 0.11811 0.01701 0.98198 0 9.60459 0.45281 8.40145 0.39606 1.13443 0.15438 0.99248 0.13506 56302.961237 0.000382 0.08514 0.01271 0.99242 0 10.09330 0.42392 8.88899 0.37334 0.85932 0.12311 0.75679 0.10842 56302.961995 0.000376 0.08240 0.01243 0.99231 0 10.48340 0.43195 9.23105 0.38035 0.86384 0.12538 0.76056 0.11039 56302.962773 0.000402 0.07787 0.01203 1.00000 0 10.10325 0.41181 8.86056 0.36114 0.78679 0.11722 0.69107 0.10298 56302.963529 0.000353 0.08920 0.01333 0.98361 0 10.51445 0.44670 9.26189 0.39349 0.93786 0.13436 0.82616 0.11836 56302.964238 0.000356 0.10030 0.01388 0.98374 0 10.87595 0.45460 9.74025 0.40714 1.09083 0.14387 0.97866 0.12909 56302.964975 0.000382 0.09254 0.01370 0.94697 0 9.82738 0.41622 8.72010 0.36924 0.90940 0.12906 0.80916 0.11475 56302.965820 0.000463 0.10198 0.01206 0.99375 0 11.04424 0.40365 9.77550 0.35732 1.12627 0.12672 0.99537 0.11199 56302.966824 0.000541 0.09675 0.01075 0.98967 0 11.09171 0.36886 9.95186 0.33096 1.07307 0.11375 0.96341 0.10212
