/* ** ** 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 54943.064775 0.000240 0.19983 0.01569 0.98795 0 26.49661 0.83847 24.24642 0.76721 5.29476 0.38044 4.84326 0.34800 54943.065307 0.000292 0.16988 0.01318 1.00000 0 25.11669 0.74505 23.11167 0.68557 4.26672 0.30594 3.92598 0.28151 54943.065863 0.000263 0.17251 0.01345 0.98901 0 27.66493 0.82397 25.45012 0.75801 4.77256 0.34381 4.39049 0.31628 54943.066375 0.000249 0.19650 0.01536 1.00000 0 25.58882 0.81569 23.54599 0.75057 5.02821 0.35887 4.62680 0.33022 54943.066838 0.000214 0.21915 0.01722 1.00000 0 26.76364 0.89757 24.62108 0.82572 5.86529 0.41667 5.39575 0.38331 54943.067292 0.000240 0.21452 0.01686 1.00000 0 24.41495 0.81233 22.46055 0.74730 5.23740 0.37285 4.81817 0.34300 54943.067767 0.000234 0.19633 0.01562 1.00000 0 26.85718 0.85795 24.71270 0.78945 5.27288 0.38421 4.85192 0.35353 54943.068241 0.000240 0.21280 0.01666 1.00000 0 24.72419 0.81567 22.75537 0.75072 5.26122 0.37360 4.84231 0.34385 54943.068730 0.000249 0.20271 0.01591 0.98837 0 25.34694 0.81245 23.31763 0.74741 5.13815 0.36805 4.72678 0.33858 54943.069248 0.000269 0.17632 0.01378 1.00000 0 26.19023 0.79347 24.09794 0.73008 4.61775 0.33266 4.24886 0.30608 54943.069838 0.000321 0.18289 0.01282 0.99173 0 26.34808 0.72934 24.24307 0.67107 4.81873 0.31020 4.43356 0.28540 54943.134234 0.000220 0.21849 0.01739 0.98684 0 26.24459 0.87932 24.29904 0.81413 5.73429 0.41407 5.30915 0.38337 54943.134708 0.000255 0.19109 0.01510 1.00000 0 25.52987 0.80790 23.40455 0.74062 4.87860 0.35334 4.47263 0.32395 54943.135246 0.000284 0.17255 0.01359 1.00000 0 25.52549 0.76746 23.19550 0.69732 4.40436 0.32054 4.00180 0.29125 54943.135802 0.000272 0.18452 0.01419 1.00000 0 25.65689 0.78516 23.23525 0.71102 4.73427 0.33394 4.28371 0.30215 54943.136430 0.000356 0.20162 0.01318 0.99977 0 25.08304 0.67800 22.99679 0.62158 5.05719 0.30106 4.63620 0.27598
