# Measurement of the Magnetic Field vector at a specific location.

# 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.
