OMEGA_COROTATE

OMEGA_COROTATE = <Quantity 2.8660944e-06 rad / s>

Default angular velocity of the MAS corotating frame, in physical unit.

MAS can be run in a frame rotating with the Sun. The dimensionless code rotation rate 0.004144 rad per time unit converts to

\[\Omega_\text{corotate} = \frac{0.004144}{T_0} \approx 2.87 \times 10^{-6}\;\text{rad s}^{-1},\]

which matches the solar sidereal rotation rate (period ≈ 25.4 days).
