In science:

The limiting sensitivity of 10−6 m−2 s−1 should be compared with the rate for cosmic rays and albedo protons and electrons to intersect the detector, which is around 5 kHz, or some nine orders of magnitude larger.
Gamma-Ray Summary Report
It is composed of three subsystems: the Anti-Coincidence Detector (ACD) is responsible for vetoing the enormous charged cosmic-ray background and the Earth albedo secondary electrons and nuclei.
Triggers and alerts with GLAST
By comparing the observed scattered intensity with the estimated intensity of the starlight incident on the cloud, it is possible to infer the albedo of the dust – the ratio of scattering cross section to extinction cross section.

However, the rear segments were strongly affected by albedo flux due to reflection from the Earth, which complicated timing analysis.

Important grain properties are the opacity, κ, the scattering albedo, ω , and the scattering asymmetry parameter, g .
On the Snow Line in Dusty Protoplanetary Disks
What sets the KMH grains apart is that they are more forward throwing (g= 0.40(R), 0.25(K )), and have higher albedo (ω= 0.50(R), 0.36(K )) at each wavelength (optical to near-IR).
On the Snow Line in Dusty Protoplanetary Disks
Our results differ from existing calculations (in that they bring the snow line even closer in), because the dust grains properties we used have higher albedo and more forward throwing.
