/* ** ** 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 55984.354774 0.000422 0.09056 0.01337 0.97945 0 8.61167 0.36507 7.73756 0.32799 0.77989 0.11030 0.70047 0.09906 55984.355532 0.000336 0.12373 0.01856 0.99138 0 7.91258 0.39451 7.06711 0.35234 0.97906 0.13847 0.87102 0.12318 55984.356253 0.000385 0.10848 0.01602 0.99248 0 8.12724 0.37641 7.21672 0.33424 0.88161 0.12363 0.78216 0.10967 55984.357028 0.000391 0.08739 0.01363 0.99259 0 9.18263 0.39528 8.16028 0.35123 0.80247 0.12027 0.71286 0.10684 55984.357778 0.000359 0.10261 0.01524 0.98387 0 8.99372 0.40801 8.00181 0.36300 0.92285 0.13052 0.82104 0.11611 55984.358605 0.000469 0.07896 0.01198 0.98148 0 8.72381 0.35032 7.76720 0.31189 0.68884 0.10079 0.61246 0.08966 55984.359598 0.000524 0.07075 0.01047 0.99448 0 8.80864 0.33562 7.78611 0.29665 0.62321 0.08916 0.55132 0.07887 55984.360564 0.000443 0.08711 0.01299 0.98039 0 8.48545 0.35577 7.61920 0.31944 0.73920 0.10574 0.66159 0.09464 55984.361386 0.000379 0.10226 0.01519 0.99237 0 8.40930 0.38184 7.54726 0.34269 0.85995 0.12162 0.77051 0.10897 55984.362205 0.000440 0.08569 0.01278 0.97368 0 8.91372 0.36942 7.89280 0.32709 0.76384 0.10939 0.67779 0.09707 55984.362960 0.000315 0.11910 0.01798 0.95413 0 8.94529 0.43178 8.02600 0.38736 1.06535 0.15239 0.95421 0.13650 55984.363715 0.000440 0.08301 0.01223 0.97368 0 9.27741 0.37601 8.22721 0.33344 0.77011 0.10904 0.68406 0.09687 55984.364508 0.000353 0.11351 0.01695 0.99180 0 8.14475 0.38948 7.29615 0.34890 0.92454 0.13076 0.82782 0.11707 55984.365211 0.000350 0.11181 0.01706 0.98347 0 8.33456 0.39707 7.46851 0.35577 0.93187 0.13507 0.83516 0.12098 55984.366111 0.000550 0.11293 0.01349 0.97368 0 8.42334 0.32030 7.45852 0.28360 0.95126 0.10772 0.84465 0.09564
