Orientation and wobble (δ) used in the simulations of myosin V stepping (see Section 2.1)

State	{θ, φ}	{β, α}	δ
Prestep	{96.7, 168.8}	{20, −20}	40
Detached head	–	–	90
Poststep	{18.9, 23.3}	{80, −85}	40

The orientations are represented in polar coordinates, in the microscope (θ, φ) and actin (β, α) frames. That is, β is the polar angle of the probe with respect to the actin filament and α is the azimuthal angle around the filaments, where α = 0 is parallel to the microscope stage and α = 90 is parallel to the optical axis of the microscope. All angles are in degrees.
