/* ** ** 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 57725.250179 0.000315 0.10572 0.01572 0.98165 0 10.02230 0.45964 8.85479 0.40610 1.05953 0.14984 0.93614 0.13239 57725.250804 0.000310 0.10940 0.01652 1.00000 0 9.63790 0.45921 8.48962 0.40449 1.05443 0.15111 0.92627 0.13276 57725.251420 0.000307 0.11428 0.01707 0.98113 0 9.45930 0.45416 8.42790 0.40464 1.08101 0.15288 0.96314 0.13621 57725.252031 0.000304 0.11030 0.01634 1.00000 0 9.99524 0.46935 8.90330 0.41808 1.10252 0.15487 0.98207 0.13795 57725.252676 0.000341 0.09225 0.01364 0.98305 0 10.51092 0.45350 9.36043 0.40386 0.96963 0.13713 0.86351 0.12212 57725.253825 0.000807 0.10744 0.00979 0.97849 0 10.35085 0.29250 9.21733 0.26047 1.11205 0.09630 0.99026 0.08575 57725.255271 0.000639 0.11640 0.01221 0.99095 0 9.33985 0.31356 8.31739 0.27923 1.08718 0.10806 0.96816 0.09623 57725.256990 0.001079 0.12428 0.00947 0.97855 0 9.88978 0.24851 8.71514 0.21898 1.22907 0.08839 1.08325 0.07789 57725.259192 0.001123 0.11280 0.00866 0.97938 0 10.39877 0.24963 9.14656 0.21957 1.17301 0.08556 1.03187 0.07526 57725.261391 0.001076 0.12562 0.00947 0.99194 0 9.93334 0.24907 8.75294 0.21945 1.24786 0.08866 1.10122 0.07824
