/* ** ** 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 59988.044146 0.000304 0.16060 0.01269 0.98095 0 28.42583 0.82016 23.56112 0.67977 4.56528 0.33578 3.78436 0.27842 59988.044777 0.000327 0.16032 0.01245 1.00000 0 27.14184 0.78335 21.95654 0.63369 4.35126 0.31360 3.53473 0.25462 59988.045480 0.000376 0.14421 0.01118 0.96923 0 27.81922 0.75473 21.64836 0.58730 4.01176 0.29133 3.12234 0.22669 59988.046186 0.000330 0.16420 0.01274 0.99123 0 27.25686 0.79254 21.42371 0.62285 4.47567 0.32200 3.51532 0.25288 59988.046863 0.000347 0.15936 0.01233 0.99167 0 26.41785 0.76422 21.06414 0.60928 4.20995 0.30217 3.35491 0.24072 59988.047532 0.000321 0.17010 0.01408 0.99099 0 25.35524 0.77411 20.23705 0.61783 4.31294 0.33178 3.44638 0.26495 59988.048220 0.000367 0.14630 0.01141 1.00000 0 26.66760 0.73980 21.17500 0.58733 3.90160 0.28447 3.09925 0.22591 59988.048970 0.000382 0.14093 0.01121 0.98485 0 26.48365 0.73178 21.07164 0.58204 3.73226 0.27837 2.97048 0.22147 59988.049661 0.000310 0.17073 0.01350 1.00000 0 27.10870 0.81868 21.41470 0.64674 4.62839 0.33826 3.65983 0.26748 59988.050327 0.000356 0.15746 0.01235 0.97561 0 26.26315 0.74657 20.76439 0.59026 4.13552 0.30217 3.26335 0.23850 59988.051010 0.000327 0.17688 0.01401 1.00000 0 24.73464 0.75614 19.59377 0.59895 4.37514 0.31972 3.46550 0.25327 59988.051698 0.000362 0.16694 0.01283 0.97717 0 25.35491 0.73618 20.02471 0.58141 4.23277 0.30127 3.35206 0.23840
