Solves system of linear equations to decompose timefield by factors. Computed S (source) and R (receiver) factors then used by sc_apply module to apply static shifts and by sc_build_vel_model to perform interactive corrections.
Choose horizon with first break picks.
Set the limits by offsets or by picks for each layer.
There are two mathematical models:
- F(i,j) = S(i)+R(j)+M(cdp)* for refracted waves
- F(i,j) = S(i)+R(j)+M(cdp)*^2 for relfected waves
In Special Conditions section set the parameters to regularize the solution.
