Typedef Documentation

GRBP_skew

Typedef for struct _GRBP_skew.

The purpose of these parameters is to ensure that a repoint request does not result in the GRB gammas coming in exactly parallel to the LAT's towers and all its cracks. Doing so would affect the resolution and efficiency. These parameters are meant to skew the repoint direction slightly off-axis.
