/* ** ** 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 58155.314586 0.000489 0.20936 0.00748 1.00000 0 62.56650 0.92751 55.87880 0.82833 13.09918 0.42608 11.70273 0.38068 58155.315521 0.000446 0.23452 0.00858 1.00000 0 60.70718 0.95765 54.17051 0.85444 14.23735 0.46990 12.70728 0.41937 58155.316441 0.000475 0.21434 0.00776 1.00000 0 62.11989 0.93382 55.83707 0.83938 13.31507 0.43878 11.96909 0.39437 58155.317408 0.000492 0.21312 0.00753 1.00000 0 60.93802 0.90649 54.96897 0.81770 12.98722 0.41645 11.71500 0.37565 58155.318374 0.000475 0.21474 0.00766 1.00000 0 62.19550 0.93214 56.12565 0.84117 13.35599 0.43226 12.05270 0.39008 58155.319314 0.000466 0.21697 0.00783 1.00000 0 62.82716 0.95161 56.32204 0.85303 13.63138 0.44623 12.22250 0.40006 58155.320246 0.000466 0.22167 0.00790 1.00000 0 62.42045 0.94748 55.51127 0.84263 13.83652 0.44637 12.30815 0.39711 58155.321207 0.000495 0.20503 0.00743 1.00000 0 62.47375 0.92043 55.89001 0.82341 12.80895 0.42389 11.45615 0.37920 58155.322147 0.000446 0.23428 0.00839 1.00000 0 61.90071 0.96758 55.09336 0.86112 14.50189 0.46715 12.90663 0.41578 58155.323067 0.000475 0.21965 0.00792 1.00000 0 61.45119 0.93425 54.63261 0.83052 13.49758 0.44119 11.99257 0.39194 58155.324016 0.000475 0.22214 0.00801 1.00000 0 60.41923 0.92526 54.07459 0.82806 13.42148 0.43815 12.01700 0.39232 58155.325426 0.000935 0.21282 0.00552 0.99381 0 61.67813 0.66653 55.04544 0.59484 13.12649 0.30944 11.71689 0.27617
