In science:

Fluke, Webster and Mortlock (1999) and Fluke, Webster and Mortlock (2000) have used a ‘ray-bundle’ method in which a discrete bundle of light rays is traced.
Significant effects of weak gravitational lensing on determinations of the cosmology from Type Ia Supernov\ae
Because of the high magnification tails in Fluke, Webster and Mortlock’s (2000) distributions, they discard those high magnification lines of sight which occur with low probability before defining the µlow and µhigh values.
Significant effects of weak gravitational lensing on determinations of the cosmology from Type Ia Supernov\ae
These magnification probability distributions are then used by Fluke and Webster (2000) to examine the effects of the weak lensing dispersion on measurements of q0 in both the empty beam (more appropriate for point particles) and full beam limits.
Significant effects of weak gravitational lensing on determinations of the cosmology from Type Ia Supernov\ae
To convert their empty beam magnification values to filled beam values, Fluke and Webster (2000) use a simple scaling relationship.
Significant effects of weak gravitational lensing on determinations of the cosmology from Type Ia Supernov\ae
Although Fluke and Webster (2000) use the median magnification values, the values are always close to unity and greater than, or equal to, unity for the empty beam case.
