Notes. Columns (2) and (3) give the equatorial coordinates [(α,   δ)2000.0]. Columns (4)–(7) list the gas kinetic temperature, core mass, beam-averaged peak H2 column density, and the volume-averaged H2 number density, respectively. In the last column we give the comments on the source classification. The virial parameter of the starless cores SMM 5 and Ori B9 N is αvir ≳ 2, and thus it is unclear if they are prestellar (Paper II).

(a)

These coordinates refer to the LABOCA peak positions after adjusting the pointing. The coordinates of our molecular-line observation target positions can be found in Table 1 of Paper II.

(b)

The first value is calculated towards the revised LABOCA peak position by using the temperature derived towards the line observation target position. The latter N(H2) value refers to the position used in molecular-line observations.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
