public class SigmaEigenvectorsCovariance extends CommentsContainer
Container for Sigma/Eigenvectors Covariance data. The positional covariance one-sigma dispersions corresponding to the major, intermediate and minor eigenvalues, followed by the associated eigenvectors. The data is presented on a single line (12 values separated by spaces). (Condition: Mandatory if ALT_COV_TYPE = CSIG3EIGVEC3)
