/* ** ** 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 58094.285840 0.000498 0.13671 0.01045 0.99419 0 18.64246 0.49183 17.02610 0.44917 2.54857 0.18280 2.32708 0.16686 58094.286786 0.000448 0.15690 0.01196 0.96774 0 18.37481 0.51176 17.05936 0.47512 2.88302 0.20447 2.67394 0.18964 58094.287701 0.000466 0.15789 0.01211 0.98137 0 17.22371 0.48662 16.01439 0.45245 2.71949 0.19393 2.52855 0.18032 58094.288580 0.000414 0.15825 0.01220 0.98601 0 19.18101 0.54248 17.83413 0.50439 3.03535 0.21765 2.82221 0.20237 58094.289454 0.000460 0.14910 0.01143 0.99371 0 18.22207 0.50557 16.87448 0.46816 2.71691 0.19424 2.51587 0.17987 58094.290357 0.000443 0.15396 0.01206 0.98693 0 18.17113 0.51196 16.82457 0.47401 2.79768 0.20453 2.59066 0.18937 58094.291231 0.000431 0.16146 0.01243 0.98658 0 18.01269 0.51528 16.74851 0.47911 2.90825 0.20792 2.70413 0.19333 58094.292058 0.000396 0.17643 0.01384 0.98540 0 17.93548 0.53636 16.67652 0.49871 3.16433 0.22947 2.94222 0.21336 58094.292845 0.000391 0.18032 0.01384 1.00000 0 17.89714 0.53982 16.64136 0.50194 3.22714 0.22773 3.00072 0.21175 58094.293635 0.000399 0.16970 0.01313 0.99275 0 18.50021 0.54722 17.20227 0.50883 3.13948 0.22454 2.91923 0.20879 58094.294388 0.000353 0.18628 0.01454 0.99180 0 18.98719 0.58567 17.65462 0.54456 3.53692 0.25361 3.28869 0.23582 58094.295123 0.000382 0.17832 0.01411 0.98485 0 18.26122 0.55185 16.97982 0.51312 3.25632 0.23807 3.02782 0.22137 58094.296002 0.000498 0.15222 0.01128 0.98837 0 18.49221 0.48891 17.19483 0.45461 2.81497 0.19478 2.61748 0.18112
