/* ** ** 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 56037.982655 0.000564 0.19149 0.01225 0.98093 0 17.84097 0.45165 16.38215 0.41474 3.41634 0.20069 3.13788 0.18435 56038.023338 0.000367 0.18386 0.01439 1.00000 0 18.64321 0.57448 17.01244 0.52422 3.42781 0.24652 3.12805 0.22498 56038.024105 0.000399 0.17178 0.01348 0.97101 0 19.04594 0.56159 17.18922 0.50679 3.27163 0.23785 2.95270 0.21460 56038.024854 0.000350 0.18671 0.01461 0.98347 0 19.87861 0.61113 17.89310 0.55002 3.71148 0.26697 3.33834 0.24011 56038.025546 0.000341 0.20272 0.01611 0.98305 0 18.53270 0.59944 16.76983 0.54236 3.75696 0.27265 3.39187 0.24620 56038.026252 0.000365 0.18436 0.01452 0.99206 0 18.88699 0.58393 17.17262 0.53085 3.48202 0.25221 3.16368 0.22904 56038.027007 0.000391 0.17296 0.01383 0.99259 0 18.35286 0.55518 16.73835 0.50631 3.17437 0.23497 2.89590 0.21440 56038.027941 0.000544 0.21069 0.01290 0.99036 0 18.71067 0.47763 16.92836 0.43208 3.94224 0.21936 3.56687 0.19841 56038.047419 0.000440 0.20606 0.01632 0.98026 0 20.24377 0.65651 12.95130 0.41969 4.17147 0.30140 2.68019 0.19313 56038.048342 0.000483 0.16848 0.01342 0.97006 0 20.90960 0.61630 14.32257 0.42214 3.52291 0.26059 2.40646 0.17785 56038.049462 0.000637 0.19190 0.01264 0.99094 0 20.74049 0.54245 13.93779 0.36443 3.98004 0.24071 2.68275 0.16211 56038.090131 0.000350 0.18225 0.01438 1.00000 0 19.48138 0.60102 17.84881 0.55062 3.55043 0.25774 3.25199 0.23601 56038.091019 0.000538 0.18710 0.01220 1.00000 0 18.27850 0.47214 16.61350 0.42905 3.41989 0.20482 3.10869 0.18618
