Notes. (1)Name of the cloud associated with each sightline. We generally favor the lower density envelopes (where we can see more stars through the clouds) over the most extinguished regions (2)Longitude of the sightline (3)Latitude of the sightline (4)Distance to the cloud. The first error term is the statistical uncertainty, while the second is the systematic uncertainty (estimated to be ≈5% in distance for nearby clouds, ≈10% in distance for faraway clouds ≳1.5 kpc, and ≈7% in distance for the NSC clouds Chamaeleon, Lupus, and Corona Australis; see Sect. A in this work and Sect. 3.6 in Zucker et al. (2019) for more discussion on the systematic uncertainties). We recommend the uncertainties be added in quadrature. (5)Whether the sightline was taken from Zucker et al. (2019) (Y) or is novel to this work (N). (6)Whether the cloud appeared in the Northern or Southern volume of the Star Formation Handbook. (7)The page in the Northern or Southern volume of the Star Formation Handbook in which the cloud appeared.

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.

Initial download of the metrics may take a while.
