/* ** ** 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 55198.310338 0.000518 0.24474 0.00894 1.00000 0 55.60031 0.89464 44.94018 0.72186 13.60775 0.44622 10.96029 0.35898 55198.311327 0.000472 0.25424 0.00933 1.00000 0 56.26221 0.92252 47.49910 0.77885 14.30437 0.46942 12.07266 0.39624 55198.312291 0.000492 0.24116 0.00873 1.00000 0 57.34502 0.91320 48.06303 0.76537 13.82930 0.44933 11.59407 0.37672 55198.313341 0.000558 0.24686 0.00826 0.99760 0 58.26043 0.86261 48.99158 0.72537 14.38214 0.43135 12.09888 0.36285 55198.377511 0.000469 0.24097 0.00855 0.98765 0 55.55755 0.86926 51.94943 0.81281 13.38762 0.42634 12.51812 0.39865 55198.378442 0.000463 0.23685 0.00856 1.00000 0 56.34418 0.88617 51.98209 0.81746 13.34517 0.43413 12.30290 0.40020 55198.379374 0.000469 0.23311 0.00827 1.00000 0 57.42876 0.89046 52.77975 0.81835 13.38694 0.42748 12.30174 0.39276 55198.380323 0.000480 0.22120 0.00797 1.00000 0 58.42144 0.88605 53.46025 0.81074 12.92301 0.42213 11.82821 0.38632 55198.381287 0.000483 0.22491 0.00802 1.00000 0 56.68380 0.86374 52.80975 0.80466 12.74849 0.41074 11.88285 0.38283 55198.382247 0.000477 0.22890 0.00820 1.00000 0 57.45461 0.88687 52.36726 0.80835 13.15123 0.42497 11.98751 0.38739 55198.383688 0.000964 0.23154 0.00589 0.99700 0 55.63091 0.61192 50.88079 0.55966 12.88069 0.29556 11.78548 0.27046
