a) Distribution of peak of 13CO(1–0) towards LDN 1569 obtained from SEST observations and Gaussian fits to the spectra. Contour levels are 0.5 to 2.0 K in steps of 0.5 K. The crosses indicate the observed positions. b) As a), but for the line integrated emission . Contour levels are 0.45 to 1.9 K km s-1 in steps of 0.45 K km s-1. The filled circles indicate the positions of the candidate emission-line stars. Offsets as in Fig. 2.
