/* ** ** 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 59921.669163 0.000260 0.16152 0.01295 1.00000 0 31.68394 0.93121 26.72601 0.78539 5.11751 0.38164 4.31660 0.32199 59921.669710 0.000286 0.15065 0.01167 0.98990 0 31.74541 0.88979 26.89514 0.75385 4.78255 0.34526 4.05595 0.29285 59921.670315 0.000318 0.13599 0.01045 1.00000 0 31.09586 0.82832 26.42463 0.70388 4.22886 0.30490 3.59340 0.25911 59921.670925 0.000292 0.15613 0.01242 1.00000 0 29.37145 0.85009 24.77461 0.71700 4.58566 0.33985 3.86427 0.28637 59921.671521 0.000304 0.14073 0.01069 1.00000 0 32.41303 0.87477 27.12506 0.73197 4.56141 0.32385 3.81783 0.27104 59921.672120 0.000295 0.14788 0.01143 1.00000 0 31.25634 0.87077 26.15933 0.72865 4.62228 0.33322 3.87523 0.27943 59921.672710 0.000295 0.14324 0.01108 1.00000 0 31.76734 0.86898 27.06971 0.74048 4.55033 0.32940 3.87725 0.28068 59921.673301 0.000295 0.15437 0.01186 1.00000 0 29.84793 0.84441 25.34406 0.71700 4.60758 0.32922 3.91250 0.27957 59921.673853 0.000258 0.17551 0.01359 1.00000 0 30.11123 0.91608 25.53263 0.77673 5.28485 0.37617 4.48168 0.31897 59921.674423 0.000312 0.14437 0.01092 0.99074 0 30.97248 0.84333 26.05587 0.70948 4.47152 0.31542 3.76327 0.26544 59921.675054 0.000318 0.13918 0.01068 1.00000 0 31.13296 0.83483 25.93734 0.69542 4.33298 0.31167 3.61161 0.25975 59921.675694 0.000321 0.14547 0.01126 0.98198 0 29.74996 0.81529 24.91890 0.68283 4.32786 0.31334 3.62825 0.26265 59921.676327 0.000312 0.14255 0.01119 1.00000 0 30.35375 0.83174 25.31750 0.69367 4.32698 0.31828 3.61000 0.26548 59921.676938 0.000298 0.14898 0.01138 0.99029 0 31.33858 0.86871 26.24281 0.72747 4.66898 0.33232 3.91048 0.27832 59921.677548 0.000312 0.14274 0.01117 0.99074 0 30.22159 0.82656 25.65116 0.70157 4.31382 0.31637 3.66247 0.26861 59921.678124 0.000263 0.16510 0.01269 0.96703 0 32.68801 0.94036 27.60039 0.79397 5.39679 0.38466 4.55771 0.32484 59921.678761 0.000373 0.12186 0.00928 0.99225 0 31.00697 0.77402 25.87082 0.64576 3.77852 0.27174 3.15389 0.22682
