Distribution of epoch position residuals  ⟨ y ⟩  of field stars (dots of different type) as a function of d for four September nights and linear dependences of  ⟨ y ⟩  on d (lines of different type) for each night. Upper panel: with initial LADC separations b. Lower panel: the same with recovered b values. Size of dots is proportional to the star brightness.
