Six arcs between four quasars were measured using very long baseline interferometry. Three methods for the leveling of such measurements are proposed: a method of correlate leveling with angles, a method of correlate leveling with spherical excesses, and a method of leveling without correlates on the basis of the spherical coordinates of the given quasar complex. A numerical example is presented.
