  We measure ejecta mass as a function of azimuthal and impact angle for 104
m/s oblique impacts into sand. We find that the ejecta mass distribution is
strongly sensitive to azimuthal angle with up to 8 times more mass in ejecta on
the downrange side compared to the uprange side. Crater radii, measured from
the site of impact, are measured at different impact and azimuthal angles.
Crater ejecta scaling laws are modified to depend on azimuthal and impact
angle. We find that crater radii are sensitive to both impact and azimuthal
angle but the ejecta mass as a function of both angles can be estimated from
the cube of the crater radius without an additional angular dependent function.
The ejecta distributions are relevant for processes that depend upon the
integrated properties of intermediate velocity impacts occurring in the outer
solar system and possibly during planetesimal formation.
