Dark nebulae in the large Magellanic Cloud. II. A 4-m survey

A survey of optically-visible dust clouds is made on a set of CTIO 4-m telescope plates of the LMC, covering 14 fields in different parts of the Cloud. The dark nebulae cataloged are, on the average, a factor of two smaller than those of the previous survey, a result of the larger scale and deeper limit of the new plate material. The 146 dark nebulae have a mean dimension of 26 pc and a mean Lynds opacity class of 2.6. Although there is a good general agreement in position with CO clouds (Cohen et al. 1987), there are areas with CO emission and no dust clouds, as well as vice versa. 5 references
