/* ** ** 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 59197.185917 0.000344 0.21488 0.01750 0.97479 0 17.16660 0.57292 15.55326 0.51910 3.68883 0.27400 3.34713 0.24875 59197.186658 0.000396 0.17973 0.01404 0.98540 0 17.87488 0.54285 16.39085 0.49773 3.21268 0.23112 2.94274 0.21165 59197.187474 0.000420 0.16878 0.01305 0.99310 0 17.88048 0.52868 16.41940 0.48548 3.01795 0.21565 2.77132 0.19803 59197.188215 0.000321 0.22587 0.01825 0.99099 0 17.16459 0.59253 15.76481 0.54421 3.87695 0.28326 3.56059 0.26015 59197.188869 0.000333 0.21494 0.01705 0.97391 0 17.87988 0.59185 16.41886 0.54349 3.84316 0.27713 3.52916 0.25449 59197.189575 0.000373 0.19444 0.01512 0.98450 0 17.77357 0.55885 16.32288 0.51324 3.45585 0.24569 3.17383 0.22564 59197.190292 0.000344 0.20907 0.01619 1.00000 0 17.79850 0.58268 16.34626 0.53514 3.72115 0.26117 3.41745 0.23986 59197.190958 0.000321 0.20958 0.01653 1.00000 0 18.58923 0.61381 17.06870 0.56360 3.89587 0.27910 3.57717 0.25627 59197.191650 0.000370 0.18729 0.01469 1.00000 0 18.04613 0.56352 16.57121 0.51746 3.37986 0.24309 3.10367 0.22323 59197.192408 0.000388 0.17123 0.01342 0.97761 0 19.10265 0.56590 17.54078 0.51963 3.27096 0.23742 3.00355 0.21801 59197.193180 0.000385 0.18182 0.01435 1.00000 0 17.71679 0.55005 16.27144 0.50518 3.22122 0.23381 2.95839 0.21473 59197.193953 0.000388 0.18225 0.01451 1.00000 0 17.47206 0.54085 16.04652 0.49673 3.18436 0.23356 2.92439 0.21450 59197.194694 0.000353 0.19246 0.01507 1.00000 0 18.41451 0.58288 16.91110 0.53529 3.54401 0.25389 3.25464 0.23316 59197.195773 0.000726 0.17233 0.00991 0.98406 0 18.57501 0.40753 17.06153 0.37432 3.20094 0.17009 2.94017 0.15623
