Property Value

Positive values indicate an error that is greater than or equal to the value in metres/second. Negative values indicate a margin for error that is less than the absolute value in metres/second. So a value of 10.0 indicates a margin for error greater than or equal to 10 m/s whereas a value of -10 indicates a margin for error that is less than 10 m/s. Null values indicate that the value was undefined by the documentation.
