Notes. 

(a)

Object radii were estimated from Gaussian fits to the column density profile (R = FWHM/2). Radii were deconvolved with a 36.6″ beam.

(b)

Masses are taken from integrating out the column density profiles. The lower limit measurements subtract the LOS material from the column density profiles. The upper limit measurements do not subtract the LOS material from the column density profiles.

(c)

Average density determined from the mass and volume.

(d)

B1-E6 and B1-E7 are truncated to measure column density unique to each source.

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.
