Fig. 4


From top to bottom: a) radial velocity curve of MWC 314 obtained with the absorption lines (dots), with the RV solution overplotted as a continuous line. b) The intensity ratio of the blue to the red peak of the Fe ii emission lines. c) Radial velocity of the Fe ii emission lines as measured from their centroids (filled dots) and as evaluated from the red and blue emission peaks (upper and lower empty circles, RV and RV). d) Radial velocity of the forbidden [Fe ii] and [N ii] lines.
