  /**
   * Container for the additional covariance metadata (optional).
   * <p>
   * Beware that the Orekit getters and setters all rely on SI units. The parsers
   * and writers take care of converting these SI units into CCSDS mandatory units.
   * The {@link org.orekit.utils.units.Unit Unit} class provides useful
   * {@link org.orekit.utils.units.Unit#fromSI(double) fromSi} and
   * {@link org.orekit.utils.units.Unit#toSI(double) toSI} methods in case the callers
   * already use CCSDS units instead of the API SI units. The general-purpose
   * {@link org.orekit.utils.units.Unit Unit} class (without an 's') and the
   * CCSDS-specific {@link org.orekit.files.ccsds.definitions.Units Units} class
   * (with an 's') also provide some predefined units. These predefined units and the
   * {@link org.orekit.utils.units.Unit#fromSI(double) fromSi} and
   * {@link org.orekit.utils.units.Unit#toSI(double) toSI} conversion methods are indeed
   * what the parsers and writers use for the conversions.
