Notes
  • For the used data sources and all abbrerviations / codes used above look here & come back with browser's back button
  • The axis ratio (a/b) is estimated by : (a/b) >= 10**(0.4*(Observed Amplitude)).
  • Reaction time is applicable just for visual observations. 'A' means that RT was applied to the timings.
  • Duration is from observation report. If the value UT3-UT2 differs from that it is also given in red color.
