redundancy_flag_level level
In the residual listing SNAP prints an @ by observations for which there is little redundancy. These are observations which only weakly checked by the other observations and fixed station coordinates. They indicate a deficiency in the network design. The redundancy is expressed by a number between 0 and 1, where 0 indicates no redundancy (the observation is unchecked) and 1 indicates perfect redundancy. The parameter of this command is:
level
Defines the redundancy level below which observations are flagged as having low redundancy. The default is 0.1.
