/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 56729.206423 0.001042 0.25395 0.02037 0.98611 0 4.87104 0.17517 4.41216 0.15867 1.23700 0.08867 1.11978 0.08027 56729.208461 0.000995 0.25683 0.02072 0.98256 0 5.03974 0.18253 4.54236 0.16450 1.29436 0.09333 1.16712 0.08415 56729.210448 0.000992 0.26784 0.02152 0.98251 0 4.88309 0.17978 4.40198 0.16206 1.30787 0.09339 1.17975 0.08424 56729.211736 0.000295 0.20598 0.03316 0.99020 0 5.21073 0.34125 4.67030 0.30587 1.07333 0.15784 0.96116 0.14136 56729.212980 0.000943 0.26603 0.02164 0.98466 0 5.17366 0.19171 4.61671 0.17106 1.37637 0.09964 1.22876 0.08894 56729.214809 0.000885 0.29115 0.02375 0.98039 0 5.06416 0.19445 4.55092 0.17473 1.47443 0.10613 1.32488 0.09534 56729.216409 0.000715 0.24008 0.02296 0.99190 0 5.28136 0.22218 4.74702 0.19969 1.26793 0.10887 1.14010 0.09789
