/* ** ** 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 59923.459656 0.000385 0.18936 0.01483 0.97744 0 28.82278 0.89319 16.16300 0.50073 5.45801 0.39255 3.05622 0.21977 59923.460463 0.000422 0.16242 0.01249 0.98630 0 31.03268 0.90425 17.03068 0.49624 5.04031 0.35872 2.77000 0.19714 59923.461279 0.000394 0.17537 0.01385 0.97059 0 30.75106 0.92279 16.89975 0.50705 5.39294 0.39384 2.96766 0.21676 59923.462020 0.000347 0.20179 0.01583 0.99167 0 30.18517 0.97851 16.62219 0.53885 6.09093 0.43518 3.35375 0.23962 59923.462795 0.000428 0.15807 0.01234 0.97973 0 31.55885 0.89969 17.25831 0.49203 4.98850 0.36238 2.72923 0.19829 59923.463643 0.000420 0.15354 0.01223 1.00000 0 31.63437 0.90610 17.46482 0.50016 4.85703 0.36094 2.67844 0.19895 59923.464531 0.000469 0.14767 0.01154 0.97531 0 30.13939 0.83721 16.73889 0.46489 4.45062 0.32511 2.47931 0.18109 59923.465368 0.000367 0.18546 0.01466 0.98425 0 31.01496 0.96973 16.96338 0.53031 5.75209 0.41745 3.14815 0.22845 59923.466201 0.000466 0.14207 0.01101 0.98137 0 31.92961 0.86593 17.53792 0.47561 4.53624 0.32933 2.49062 0.18073 59923.467361 0.000694 0.16033 0.00979 0.99157 0 30.93027 0.69857 17.06559 0.38542 4.95901 0.28142 2.73568 0.15526
