Notes. Polarisation values are reported both before (P_{TDE + host}, θ_{TDE + host}) and after subtraction of the host galaxy’s contribution (P_TDE, θ_TDE). The S/N column is the average signal-to-noise ratio at which the sources were detected in each image of the final eight-frame dataset.

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.
