/* ** ** 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 59742.220026 0.000350 0.16295 0.01269 0.97521 0 22.27249 0.63755 20.54718 0.58816 3.62938 0.26289 3.35042 0.24269 59742.220750 0.000373 0.15185 0.01181 1.00000 0 21.94990 0.62025 20.18829 0.57043 3.33303 0.24144 3.06472 0.22199 59742.221467 0.000344 0.15701 0.01227 0.99160 0 22.97215 0.66308 21.23181 0.61284 3.60682 0.26195 3.33344 0.24209 59742.222118 0.000307 0.16998 0.01328 1.00000 0 23.87216 0.71740 21.92525 0.65896 4.05773 0.29276 3.72807 0.26894 59742.222784 0.000359 0.15784 0.01229 0.99194 0 22.02945 0.62951 20.36389 0.58192 3.47711 0.25186 3.21422 0.23282 59742.223724 0.000582 0.16023 0.00950 0.99560 0 22.51225 0.50310 20.81002 0.46506 3.60724 0.19817 3.33448 0.18318
