/* ** ** 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 55602.444483 0.000530 0.08563 0.01996 0.97268 0 3.07410 0.20283 2.62680 0.17331 0.26322 0.05886 0.22509 0.05033 55602.445716 0.000703 0.06771 0.01546 0.96296 0 3.09656 0.17616 2.62704 0.14944 0.20966 0.04636 0.17774 0.03929 55602.446998 0.000579 0.08544 0.01991 0.98000 0 2.81899 0.18528 2.38952 0.15704 0.24086 0.05386 0.20442 0.04571 55602.447999 0.000422 0.12650 0.03006 0.98630 0 2.59341 0.20840 2.20144 0.17690 0.32807 0.07336 0.27824 0.06222 55602.448792 0.000370 0.13333 0.03223 1.00000 0 2.72302 0.22833 2.31303 0.19392 0.36306 0.08230 0.30927 0.07009 55602.449585 0.000422 0.12548 0.02979 0.97260 0 2.66987 0.21262 2.24998 0.17917 0.33501 0.07492 0.28216 0.06309 55602.450459 0.000451 0.11027 0.02597 0.97436 0 2.83250 0.20956 2.39217 0.17696 0.31233 0.06984 0.26360 0.05894 55602.451260 0.000350 0.12852 0.03057 0.97521 0 3.10916 0.25235 2.62939 0.21341 0.39958 0.08935 0.33955 0.07593 55602.452015 0.000405 0.12355 0.02966 0.96429 0 2.82380 0.22345 2.37776 0.18816 0.34887 0.07908 0.29324 0.06646 55602.452724 0.000304 0.19249 0.04771 0.98095 0 2.39232 0.24016 2.00029 0.20079 0.46049 0.10436 0.38434 0.08711 55602.453644 0.000616 0.07320 0.01696 0.96714 0 3.15412 0.19082 2.65176 0.16041 0.23087 0.05163 0.19450 0.04349 55602.454790 0.000530 0.09112 0.02126 0.96175 0 2.96384 0.19766 2.50187 0.16684 0.27006 0.06039 0.22765 0.05090 55602.455762 0.000443 0.12910 0.02831 0.96732 0 2.98244 0.21925 2.54663 0.18720 0.38504 0.07955 0.32868 0.06791
