Overview of all 12 model classes.

Model name Description
PL1 + PL2 G1&G2: singular PL profiles
PL1 + PL2 + γext G1&G2: singular PL profiles, external shear
PL1 + cPL2 G1: singular PL profile, G2: cored PL profile
PL1 + cPL2 + γext G1: singular PL profile, G2: cored PL profile, external shear
cPL1 + cPL2 G1&G2: cored PL profiles
cPL1 + cPL2 + γext G1&G2: cored PL profiles, external shear
PL1 + PL2 + SIS G1&G2: singular PL profiles, SIS px without positional prior
PL1 + PL2 + NIS G1&G2: singular PL profiles, NIS without positional prior
PL1 + PL2 + rSIS G1&G2: singular PL profiles, SIS px with positional prior
PL1 + PL2 + rNIS G1&G2: singular PL profiles, NIS with positional prior
PL1 + PL2 + rSIS + γext G1&G2: singular PL profiles, SIS px with positional prior, external shear
PL1 + PL2 + rNIS + γext G1&G2: singular PL profiles, NIS with positional prior, external shear

Notes. The positional prior on the SIS and NIS models has a Gaussian distribution and is centred in the region where additional images were predicted.

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.
