/* ** ** 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 57064.048728 0.000457 0.32831 0.01222 1.00000 0 41.06931 0.75554 37.97174 0.69855 13.48363 0.43619 12.46837 0.40333 57064.049666 0.000480 0.31861 0.01187 1.00000 0 40.23347 0.73470 37.21297 0.67954 12.81859 0.41615 11.85189 0.38478 57064.050597 0.000451 0.34298 0.01270 1.00000 0 40.38488 0.75893 37.17550 0.69857 13.85101 0.44214 12.75732 0.40719 57064.051500 0.000451 0.33555 0.01252 1.00000 0 41.20353 0.76669 37.66275 0.70074 13.82578 0.44736 12.64333 0.40904 57064.052403 0.000451 0.33793 0.01258 1.00000 0 40.87656 0.76281 37.50159 0.69979 13.81331 0.44506 12.67276 0.40829 57064.053338 0.000483 0.32089 0.01188 1.00000 0 39.88150 0.72775 36.88509 0.67306 12.79753 0.41208 11.83591 0.38108 57064.054698 0.000877 0.33792 0.00904 0.99919 0 40.20648 0.54101 37.17179 0.50016 13.58644 0.31419 12.56155 0.29046 57064.121544 0.000558 0.29742 0.01086 1.00000 0 38.78897 0.67788 34.58788 0.60443 11.53664 0.37002 10.28741 0.32996 57064.123187 0.001085 0.30025 0.00775 1.00000 0 39.41085 0.48857 35.12403 0.43540 11.83308 0.26805 10.54725 0.23890
