/* ** ** 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 56387.081860 0.000330 0.14098 0.01112 0.98246 0 26.93018 0.72667 24.55549 0.66255 3.79651 0.28132 3.46409 0.25656 56387.082517 0.000327 0.13743 0.01090 1.00000 0 27.11519 0.73543 24.85770 0.67421 3.72637 0.27782 3.41740 0.25479 56387.083122 0.000278 0.16040 0.01243 1.00000 0 28.09718 0.81121 25.79733 0.74481 4.50673 0.32419 4.13784 0.29766 56387.083721 0.000321 0.14849 0.01131 0.99099 0 26.72910 0.73556 24.54128 0.67535 3.96903 0.28179 3.64416 0.25873 56387.084346 0.000304 0.14960 0.01134 1.00000 0 28.21706 0.77565 25.79019 0.70891 4.22115 0.29819 3.85585 0.27239 56387.084948 0.000298 0.15306 0.01200 1.00000 0 27.24557 0.77265 24.82844 0.70400 4.17019 0.30476 3.80198 0.27786 56387.085590 0.000344 0.13242 0.01035 1.00000 0 26.94003 0.70995 24.73528 0.65185 3.56752 0.26247 3.27556 0.24099 56387.086264 0.000330 0.15026 0.01149 0.99123 0 25.69956 0.71591 23.47269 0.65385 3.86149 0.27486 3.52969 0.25123 56387.086924 0.000330 0.14204 0.01086 0.97368 0 27.57706 0.73666 25.17550 0.67252 3.91692 0.28062 3.57695 0.25628 56387.087589 0.000336 0.14055 0.01116 0.99138 0 26.02224 0.70969 23.89236 0.65160 3.65731 0.27268 3.35796 0.25036 56387.088281 0.000356 0.13318 0.01015 0.99187 0 26.63194 0.69441 24.43334 0.63707 3.54683 0.25412 3.25444 0.23317 56387.088975 0.000339 0.14538 0.01141 0.99145 0 25.40524 0.70391 23.21762 0.64329 3.69352 0.27109 3.37754 0.24782 56387.089655 0.000341 0.14443 0.01122 1.00000 0 25.28268 0.69447 23.21324 0.63762 3.65151 0.26546 3.35263 0.24373 56387.090327 0.000330 0.14843 0.01148 0.99123 0 25.94279 0.71895 23.68375 0.65629 3.85071 0.27817 3.51702 0.25401 56387.091010 0.000353 0.13277 0.01038 0.98361 0 26.75538 0.70611 24.44209 0.64499 3.55224 0.26143 3.24826 0.23898 56387.091681 0.000318 0.14834 0.01150 0.99091 0 26.63623 0.73820 24.45573 0.67777 3.95116 0.28611 3.62771 0.26268 56387.092517 0.000518 0.13491 0.00859 0.98324 0 26.02627 0.56965 23.89371 0.52297 3.51114 0.20991 3.22344 0.19271
