/* ** ** 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 57846.092843 0.000590 0.16681 0.01314 0.98039 0 13.03439 0.38223 11.74561 0.34442 2.17421 0.15889 1.95841 0.14307 57846.094101 0.000668 0.15370 0.01202 0.99567 0 12.34816 0.35089 11.14527 0.31671 1.89792 0.13826 1.71167 0.12472 57846.095389 0.000619 0.16247 0.01269 0.98131 0 12.77980 0.36943 11.53894 0.33352 2.07638 0.15068 1.87371 0.13599 57846.096729 0.000720 0.14322 0.01111 0.97590 0 12.52181 0.34178 11.27370 0.30771 1.79335 0.13016 1.61925 0.11752 57846.098048 0.000599 0.17569 0.01358 0.98551 0 12.26895 0.36933 11.13088 0.33507 2.15553 0.15341 1.95524 0.13916 57846.099252 0.000605 0.15924 0.01248 0.99522 0 13.15498 0.37890 11.88275 0.34224 2.09474 0.15263 1.89271 0.13791 57846.100979 0.001123 0.16357 0.00952 0.98597 0 12.56919 0.27267 11.35554 0.24633 2.05598 0.11099 1.85757 0.10027 57846.159724 0.000553 0.18456 0.01435 0.99476 0 12.35411 0.37904 11.33953 0.34790 2.28006 0.16291 2.09288 0.14954 57846.161367 0.001091 0.15619 0.00900 0.99469 0 13.00901 0.27690 12.02191 0.25589 2.03193 0.10879 1.87775 0.10053
