Workspace Variable covmat_sx

Covariance matrix of a priori distribution

This covariance matrix describes the Gaussian a priori distribution
for an OEM retrieval. It is represented using a symmetric block matrix.
covmat_sx can be used in two ways: Either with a block for each retrieval
quantity or with a single block containing the full covariance matrix.

Using a single block for each retrieval quantity has is advantageous for
if the retrieval quantities are assumed to be independent. In this case,
the covariance blocks can be added separately for each quantity and will
allow optimizing matrix multiplications and inverses required for the OEM
calculation.

The other case of using a single-block covariance matrix is supported
for convenience as well.

Usage:   Used by inversion methods.

Dimensions: 
     [ x, x ]
