Detailed Description

If the covariance of the measurement is known, it should be filled in. If all you know is the variance of each measurement, e.g. from the datasheet, just put those along the diagonal. A covariance matrix of all zeros will be interpreted as "covariance unknown", and to use the data a covariance will have to be assumed or gotten from some other source.

magneticField is a structured value type usable in QML. It maps directly to the sensor_msgs::msg::MagneticField ROS 2 message type.

Construct a magneticField in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.
