CameraShakerVolume question

[Madin 11]

	<xs:complexType name="CameraShakerVolumeFXNugget">
		<xs:complexContent>
			<xs:extension base="FXNugget">
				<xs:attribute name="Radius"
											type="SageReal" />
				<xs:attribute name="Duration"
											type="Time" />
				<xs:attribute name="Amplitude"
											type="Angle" />
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>

What does the 'Amplitude' attribute do?

I do not understand in practical terms what difference is made, depending on what the angle value is.

 

Thanks for any help!
