FCOV: Full Covariance Matrix

This record specifies whether to compute the full covariance matrix for an adjustment, or to compute only the part corresponding to the lines in the network connected by observations. Usually only the connected part is required and if this option is set to NO (the default) the adjustment will be performed faster for large networks.

The format of the FCOV record is as follows:

Columns 002-005: FCOV
Columns 007-009: YES/NO

Note that this record overrides the corresponding setting in the options file used for the network processing. It is provided for backward compatibility and is not normally used.
