The editor is used for the input of both network design data (station, target, code)
and adjustment data (station, target, code, observations). It is also possible to
create the observations file (name.obs) automatically by reading data of self-
registering instruments in the computer.
Module CSCAN allows for the creation of an option file (name.opt). This file
contains parameters and switches defining how to use the program. A user may
choose options interactively like:
- a design or adjustment of a network;
- a free network or constrained network;
- a choice of two base points (choice of an S-base);
- a parameter criterion matrix;
- a parameter substitute matrix;
- a distance dependant standard deviation distances;- onestandard deviation
for all distances;
- idem for all directions;
- the creation of a plot file (drawing the network);
- etc.
