The inclination angle i is expressed in degrees; $v \sin i$ is the projected rotational velocity, expressed in km s^-1; $A_{\rm p}$ is the amplitude of the radial part of the pulsation velocity, expressed in km s^-1; and $v_{\rm r,max}$ and $v_{\rm t,max}$ are, respectively, the maximum radial and tangential surface velocity due to the mode, expressed in km s^-1.
