Fig. 2
Selection of stacked CO line profiles from observed spectra (Sect. 2). The v1 lines are shown in black, v2 lines in blue. Gaps visible in some line profiles are due to telluric absorption. Disk inclinations are between 20 and 50 deg for all these objects. In HD 31648, the RCO is taken for the broad component defined by the line wings.
