Table 5.
Modelled lens and source parameter values for the different configurations of the composite mock data (presented in Sect. 3.2.4), with kinematic data having a signal-to-noise of 15 in the brightest pixel and binned to have a signal-to-noise of 30 in each bin (shown in Fig. 11).

Notes. The model presented are that including both the lensing and dynamics constraints (LD composite), that including only the lensing ones (L composite), and the two power-law models, with lensing and dynamics constraints (LD power-law) and with those from lensing only (L power-law). Parameters are presented with the 1σ uncertainties.
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.
