Notes.The listed knots can be identified in Fig. 2.(a)Following the notation used in Beltrán et al. (2009). (b)The random error is estimated as the line width divided by line S/N; the systematic component of uncertainty (due to the wavelength calibration uncertainty) is indicated in brack–ets. (c)The knots listed below were recorded simultaneously in the same frame.
