/* ** ** 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 57869.298349 0.000344 0.22286 0.01828 0.98319 0 24.75656 0.84599 15.05295 0.51139 5.51726 0.41141 3.31333 0.24577 57869.299027 0.000333 0.21544 0.01750 1.00000 0 24.49687 0.83304 15.67420 0.53162 5.27773 0.38943 3.38711 0.24952 57869.299605 0.000246 0.26982 0.02168 1.00000 0 25.31846 0.95296 17.45971 0.65700 6.83130 0.48509 4.71544 0.33486 57869.300149 0.000298 0.22391 0.01768 1.00000 0 25.31765 0.87319 17.37960 0.59940 5.66896 0.40255 3.89138 0.27634 57869.300754 0.000307 0.21214 0.01725 0.99057 0 25.92616 0.87449 17.48805 0.58990 5.49992 0.40697 3.71108 0.27452 57869.301341 0.000281 0.22954 0.01863 1.00000 0 25.64833 0.90135 17.57878 0.61776 5.88725 0.43083 4.03481 0.29520 57869.301911 0.000289 0.22870 0.01905 0.98000 0 25.18183 0.88541 17.13144 0.60231 5.75903 0.43476 3.91927 0.29596 57869.302481 0.000281 0.22510 0.01833 0.98969 0 25.88736 0.89567 18.03486 0.62417 5.82725 0.42942 4.05748 0.29890 57869.303057 0.000295 0.20974 0.01708 0.99020 0 25.55934 0.85629 18.27264 0.61188 5.36094 0.39777 3.83822 0.28470 57869.303647 0.000295 0.23588 0.01903 1.00000 0 24.48483 0.86692 16.69877 0.59119 5.77542 0.41876 3.93665 0.28540 57869.304212 0.000269 0.23723 0.01950 0.97849 0 26.46529 0.93724 17.96816 0.63626 6.27826 0.46562 4.26000 0.31599 57869.304819 0.000339 0.20868 0.01648 1.00000 0 24.01621 0.79363 16.52301 0.54603 5.01176 0.35947 3.44659 0.24721 57869.305468 0.000310 0.18996 0.01565 1.00000 0 27.47412 0.89146 18.78380 0.60959 5.21887 0.39531 3.57089 0.27041 57869.306084 0.000307 0.19767 0.01619 0.98113 0 27.28163 0.88540 18.68314 0.60624 5.39273 0.40566 3.69177 0.27764 57869.306663 0.000272 0.24282 0.01968 0.98936 0 25.28632 0.90786 17.41344 0.62520 6.14010 0.44610 4.22833 0.30725 57869.307238 0.000304 0.21372 0.01743 0.99048 0 25.18895 0.85358 17.44152 0.59097 5.38331 0.39922 3.72750 0.27649 57869.307814 0.000272 0.24319 0.02033 0.98936 0 24.71864 0.90301 16.98886 0.62052 6.01133 0.45209 4.12843 0.31048 57869.308381 0.000295 0.23678 0.01924 0.98039 0 23.87697 0.84456 16.53147 0.58478 5.65351 0.41360 3.91376 0.28634 57869.309180 0.000503 0.22589 0.01368 0.98851 0 25.60419 0.66925 17.53779 0.45835 5.78366 0.31603 3.96261 0.21652
