Units of covariance matrix read from OPM/OMM
When reading data from an OPM or OMM, the state vector is read in m and m/s, but the covariance matrix is read in km^2, km^2/s and km^2/s^2. I think inconsistency should be avoided, so I propose you to change the ODMParser class to read the covariance matrix also in m^2, m^2/s and m^2/s^2.
