Hello there,

sigma_BN is the 3x1 Modified Rodrigues Parameters (MRP) vector parameterizing the [BN] direction cosine matrix (DCM). [BN] converts N-frame vector coordinates into the B frame, as in

vector_B_frame_coordinates = BN @ vector_N_frame_coordinates

Basilisk.utilities.RigidBodyKinematics provides the so-called MRP2C function that returns the DCM parameterized by the provided MRP set. A C-equivalent is also provided in the Basilisk code base.
