a) Distribution of peak of ¹²CO(1–0) towards LDN 1569 obtained from KOSMA observations and Gaussian fits to the spectra. Contour levels are 0.5–4 K in steps of 0.5 K. b) As a), but for the line-integrated emission . Contour levels are 1.5–9.0 K km s^-1 in steps of 1.5 K km s^-1. Offsets are in arcminutes relative to 4^h02^m25.0^s, 01°18′17′′ (J2000). The filled circles indicate the positions of the candidate emission-line stars.
