a) Distribution of peak of 12CO(1–0) towards LDN 1569 obtained from SEST observations obtained from Gaussian fits to the spectra. Contour levels are 1–6 K in steps of 1 K. b) As a), but for the line-integrated emission . Contour levels are 1.5–10.5 K km s-1 in steps of 1.5 K km s-1. The filled circles indicate the positions of the candidate emission-line stars. Offsets as in Fig. 2.
