4.6 Table covmat

Values of cluster covariance matrix are stored in covmat table. Attributes conf_id, ccluster identifies covariance matrix. Value position in matrix is specified by rind and cind fields.

• conf_id is id of configuration which cluster belongs to.
• ccluster is id of cluster which matrix belongs to.
• rind is row number in covariance matrix
• cind is column number covariance matrix
• val is value itself (variance or covariance).

Values rind and cind have to respect dim and band specified in table clusters. If value in covariance matrix is not specified (record is missing), it is considered to be zero.

Example (table contents):

conf_id|ccluster|rind|cind|val
