/* ** ** 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 59141.813949 0.000347 0.32935 0.01242 1.00000 0 56.99731 1.05744 49.85295 0.92468 18.77229 0.61649 16.41308 0.53904 59141.814632 0.000336 0.33801 0.01263 1.00000 0 58.35312 1.10011 50.58377 0.95360 19.72373 0.63611 17.09867 0.55150 59141.815338 0.000370 0.32077 0.01186 1.00000 0 55.98286 1.02305 48.49328 0.88616 17.95777 0.57711 15.55031 0.49975 59141.816058 0.000350 0.32452 0.01207 1.00000 0 58.58880 1.07866 50.64609 0.93237 19.01330 0.61444 16.44209 0.53141 59141.816773 0.000365 0.31349 0.01148 1.00000 0 58.21368 1.04975 50.62358 0.91283 18.24944 0.58196 15.86824 0.50602 59141.817508 0.000370 0.30344 0.01125 1.00000 0 59.01189 1.05337 50.87549 0.90813 17.90635 0.58178 15.44132 0.50168 59141.818231 0.000353 0.32320 0.01206 1.00000 0 58.65425 1.07973 50.18598 0.92374 18.95732 0.61545 16.21715 0.52660 59141.819013 0.000428 0.31284 0.01086 0.99995 0 57.39533 0.97145 49.75877 0.84222 17.95553 0.54397 15.56251 0.47141
