Velocity-space distribution

f₀ over (vx, vy), remaining velocity axes integrated out, at logical position η = (0.5, 0.5, 0.5).

Reduced profiles

The distribution along each velocity axis, with every other phase-space axis integrated out.

Parameters

Constructor defaults. Moments are given as a background value (a float or a callable) paired with an optional perturbation.
