/* ** ** 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 59920.015908 0.000396 0.11555 0.00881 1.00000 0 29.11074 0.71685 24.96525 0.61481 3.36370 0.24260 2.88481 0.20807 59920.016625 0.000321 0.14528 0.01141 0.97297 0 29.22822 0.80266 24.88222 0.68331 4.24623 0.31245 3.60899 0.26554 59920.017285 0.000339 0.13976 0.01070 0.98291 0 29.49721 0.78718 24.81331 0.66206 4.12258 0.29584 3.47153 0.24909 59920.017957 0.000333 0.13134 0.01018 1.00000 0 30.75920 0.80863 26.07950 0.68559 4.03981 0.29450 3.42252 0.24949 59920.018648 0.000359 0.13017 0.00995 0.98387 0 29.52229 0.76161 24.99732 0.64486 3.84305 0.27643 3.25592 0.23423 59920.019340 0.000333 0.13939 0.01071 1.00000 0 29.04826 0.78574 24.78567 0.67040 4.04916 0.29127 3.45411 0.24848 59920.020037 0.000365 0.12912 0.01002 0.99206 0 28.28871 0.73685 24.26830 0.63213 3.65252 0.26696 3.13270 0.22897 59920.020749 0.000347 0.13142 0.01021 1.00000 0 29.13479 0.77001 24.83851 0.65642 3.82885 0.27983 3.26323 0.23851 59920.021458 0.000362 0.12547 0.00996 0.98400 0 29.13629 0.75044 24.87651 0.64068 3.65559 0.27443 3.12458 0.23456 59920.022164 0.000344 0.13364 0.01035 0.99160 0 29.48254 0.78056 25.23466 0.66809 3.93998 0.28685 3.37105 0.24540 59920.023069 0.000561 0.14960 0.00867 0.99312 0 29.69035 0.61323 24.95600 0.51542 4.44156 0.24056 3.73317 0.20217 59920.296116 0.000347 0.14348 0.01098 1.00000 0 34.19428 0.93303 23.37022 0.63612 4.90603 0.35090 3.34210 0.23823 59920.296810 0.000347 0.14959 0.01149 1.00000 0 36.72628 1.02731 22.28245 0.62312 5.49393 0.39282 3.32541 0.23764 59920.297542 0.000385 0.14436 0.01117 0.97744 0 36.82352 1.00440 21.08963 0.57513 5.31597 0.38500 3.04176 0.22025 59920.298283 0.000356 0.14514 0.01135 1.00000 0 37.77920 1.05080 21.94641 0.61028 5.48316 0.40073 3.18386 0.23268 59920.298989 0.000350 0.15522 0.01225 0.99174 0 37.28333 1.06848 20.91851 0.59941 5.78726 0.42570 3.24837 0.23897 59920.299692 0.000353 0.16022 0.01265 0.99180 0 35.05198 1.01775 20.25053 0.58792 5.61616 0.41223 3.23808 0.23757 59920.300714 0.000668 0.15425 0.00888 0.99567 0 35.90557 0.75497 20.44193 0.42978 5.53838 0.29666 3.15107 0.16879
