Notes. For all resolved scale heights, we show the median h_HWHM, with uncertainties showing the 16th and 84th percentiles. The parametric scale heights are from the fiducial models shown in Table 2; sources marked with N/A do not have any vertical parametric models. For scale heights fitted with frank and rave, we show upper limits if the PDF only approaches zero at large h_σ, and we note the aspect ratio as unconstrained if the PDF does not approach zero at large h_σ.

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.
