/* ** ** 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 56276.160904 0.000341 0.08871 0.01328 0.94915 0 12.11052 0.50405 10.08045 0.41916 1.07427 0.15448 0.89585 0.12878 56276.162339 0.001094 0.10188 0.00784 0.98413 0 12.59656 0.29087 10.35471 0.23907 1.28331 0.09422 1.05285 0.07730 56276.163846 0.000414 0.09387 0.01218 0.98601 0 12.77054 0.47975 10.31425 0.38737 1.19875 0.14883 0.96854 0.12029 56276.164657 0.000396 0.09630 0.01233 0.98540 0 12.62732 0.48407 10.32614 0.39583 1.21598 0.14856 0.99425 0.12147 56276.165383 0.000330 0.08738 0.01289 0.98246 0 12.48226 0.52338 10.23687 0.42924 1.09072 0.15425 0.89435 0.12648 56276.166063 0.000350 0.08140 0.01229 0.98347 0 12.42458 0.51326 10.15177 0.41933 1.01141 0.14691 0.82632 0.12003 56276.166911 0.000492 0.09526 0.01129 0.98235 0 12.53614 0.42996 10.23969 0.35121 1.19418 0.13545 0.97369 0.11039 56276.167755 0.000353 0.07483 0.01188 1.00000 0 12.64423 0.51511 10.36728 0.42235 0.94622 0.14514 0.77592 0.11900 56276.168473 0.000365 0.07729 0.01226 1.00000 0 11.86310 0.48521 9.71890 0.39751 0.91686 0.14058 0.75128 0.11522 56276.169196 0.000359 0.09113 0.01283 0.97581 0 13.04119 0.52106 10.58960 0.42308 1.18845 0.16049 0.96306 0.13003 56276.169859 0.000304 0.08342 0.01261 1.00000 0 13.71632 0.57424 11.22230 0.46982 1.14423 0.16622 0.93649 0.13604 56276.171176 0.001013 0.10245 0.00808 0.97714 0 12.50119 0.30030 10.23157 0.24578 1.28072 0.09617 1.04902 0.07877
