Double lens model parameters.

Quantity Unit Value

t 0 6046.87 ± 0.12
u 0 1.432 ± 0.032
t E d 20.69 ± 0.35
ρ
α deg 20.17 ± 0.20
s 4.405 ± 0.069
q 0.01650 ± 0.00055
F s / F base 0.981 ± 0.054

χ2/ d.o.f. 2898.21 / 3130

Notes. The parameter Fs/Fbase indicates ratio of source flux to baseline flux in the I-band. The value of u0 is greater than one, hence, the host subevent would not normally be counted for the optical depth calculations.

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.
