Notes.
ID is the identifier used in the model. These identifiers are identical to the ones introduced by Qin et al. (2011). Note: some of these objects identified by Qin et al. (2011) show an elongated intensity structure. We recover these objects with a superposition of several spherical symmetric clumps. We distinguish these components by adding additional lowercase letters to the identifier introduced by Qin et al. (2011).
RA is the right ascension of the density component given in units of hours:minutes:seconds in the equatorial coordinate system.
Dec is the declination of the density component given in units of degrees:arcminutes:arcseconds in the equatorial coordinate system.
dz is the displacement along the line of sight with respect to the model center. The z-axis is oriented such that it points towards the observer.
r0 is the radius defining the component, as described in Eq. (4).
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.
