/* ** ** 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 59310.108183 0.000822 0.12425 0.00961 0.98239 0 19.23203 0.49327 11.43400 0.29124 2.38962 0.17442 1.41025 0.10236 59310.110000 0.000995 0.11331 0.00882 0.96512 0 18.89582 0.46346 10.33494 0.25344 2.14109 0.15817 1.17487 0.08675 59310.111815 0.000819 0.13988 0.01098 0.98233 0 18.37164 0.50198 10.01115 0.27339 2.56983 0.18903 1.40236 0.10314 59310.113525 0.000891 0.12652 0.00954 0.99675 0 19.14615 0.49609 10.37057 0.26867 2.42242 0.17163 1.31229 0.09293 59310.115275 0.000859 0.13646 0.01053 0.97643 0 18.47990 0.49173 9.97417 0.26533 2.52176 0.18259 1.36366 0.09872 59310.117095 0.000961 0.12392 0.00958 0.97892 0 18.59341 0.46736 9.96111 0.25033 2.30415 0.16841 1.23161 0.09006
