/* ** ** 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 56048.185685 0.000483 0.10995 0.01310 0.98802 0 13.66779 0.51342 8.81266 0.32874 1.50271 0.16998 0.98302 0.11030 56048.186486 0.000318 0.10859 0.01594 0.99091 0 13.48581 0.61889 8.98155 0.41213 1.46449 0.20423 0.97344 0.13573 56048.187157 0.000353 0.08950 0.01321 0.96721 0 14.09031 0.59723 9.48634 0.40206 1.26115 0.17836 0.84887 0.12005 56048.187817 0.000307 0.10238 0.01599 0.98113 0 13.40339 0.62489 9.01158 0.42012 1.37221 0.20456 0.92324 0.13766 56048.189252 0.001123 0.12041 0.00929 0.97423 0 12.66971 0.31418 8.57209 0.21256 1.52551 0.11147 1.03252 0.07545 56048.190711 0.000336 0.09740 0.01462 0.98276 0 13.35613 0.59545 8.94129 0.39857 1.30092 0.18642 0.86956 0.12459 56048.192189 0.001143 0.12226 0.00927 0.96962 0 12.78201 0.31657 8.46262 0.20959 1.56274 0.11195 1.03529 0.07417 56048.193682 0.000350 0.09638 0.01482 0.98347 0 12.67156 0.56831 8.46857 0.37977 1.22125 0.17967 0.81559 0.11999 56048.194345 0.000312 0.10305 0.01548 0.96296 0 13.76127 0.62324 9.24637 0.41871 1.41811 0.20316 0.95317 0.13657 56048.195248 0.000590 0.10619 0.01164 0.97059 0 13.65400 0.45405 9.10756 0.30284 1.44990 0.15146 0.96535 0.10084
