When the luminous source is the CMB the lensing effect essentially re-maps the temperature field according to
unlensed lensed
CMB Temperature Lensing
We phenomenologically uncoupled weak lensing from primary anisotropies by introducing a new parameter AL that scales the
lensing potential such as
bull AL=0 corresponds to a theory ignoring lensingbull AL=1 corresponds to the standard weak lensing scenario
Analysis Method
AL can also be seen like a fudge parameter controlling the amount of smoothing of the peaks In fact in this figure we can see that the curves with increasingly smoothed peak structures correspond to analysis with increasingly values of AL (0 1 3 6 9)

When the luminous source is the CMB the lensing effect essentially re-maps the temperature field according to
unlensed lensed
CMB Temperature Lensing
We phenomenologically uncoupled weak lensing from primary anisotropies by introducing a new parameter AL that scales the
lensing potential such as
bull AL=0 corresponds to a theory ignoring lensingbull AL=1 corresponds to the standard weak lensing scenario
Analysis Method
AL can also be seen like a fudge parameter controlling the amount of smoothing of the peaks In fact in this figure we can see that the curves with increasingly smoothed peak structures correspond to analysis with increasingly values of AL (0 1 3 6 9)

Letting the lensing parameter vary the obtained constraints are
