/* ** ** 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 58102.242705 0.000425 0.14526 0.01098 0.99320 0 21.19185 0.57648 18.98843 0.51653 3.07843 0.21714 2.75801 0.19454 58102.243530 0.000399 0.15304 0.01167 0.99275 0 21.57315 0.60096 19.14304 0.53326 3.30164 0.23447 2.92593 0.20774 58102.244346 0.000417 0.14410 0.01095 0.99306 0 22.29893 0.61178 19.53916 0.53601 3.21328 0.22759 2.81718 0.19951 58102.245191 0.000428 0.14645 0.01127 0.97297 0 21.45140 0.58370 18.84453 0.51275 3.14155 0.22604 2.75847 0.19844 58102.245987 0.000367 0.17482 0.01374 1.00000 0 19.95942 0.60167 17.74122 0.53480 3.48936 0.25333 3.09763 0.22491 58102.246684 0.000330 0.18994 0.01513 1.00000 0 20.38239 0.64400 18.06422 0.57069 3.87152 0.28310 3.43494 0.25106 58102.247824 0.000810 0.14895 0.00825 0.99416 0 21.14223 0.41828 18.79132 0.37174 3.14904 0.16289 2.79838 0.14473 58102.313565 0.000367 0.16870 0.01313 0.99213 0 20.07262 0.59317 18.60581 0.54983 3.38618 0.24392 3.13880 0.22610 58102.314320 0.000388 0.15701 0.01230 0.99254 0 20.24287 0.57963 18.77340 0.53755 3.17841 0.23181 2.94765 0.21498 58102.315118 0.000411 0.14991 0.01158 0.99296 0 20.16840 0.56283 18.71068 0.52215 3.02342 0.21779 2.80489 0.20205 58102.316093 0.000564 0.15791 0.01015 1.00000 0 20.09480 0.47649 18.64291 0.44207 3.17318 0.18954 2.94391 0.17584
