Figure 4:
Computation of
values from a simple model of
1115+080, taken from Saha & Williams (2003). The top two panels show an image
morphology similar to 1115+080, and the corresponding source position.
The lower panel shows
against
for
source positions along the two caustics. (The horizontal axis is not
labelled because
has arbitrary units:
arcsec2, steradians, etc.) The lower loop corresponds to the
diamond caustic and the upper loop corresponds to the outer
caustic. Hence quads are below the lower loop and doubles are between
the two loops. |
