too simple off-line protocol: measure day 1, correct on days 2,3,… without new measurements, what to do in following fractions?

E(1) = 8 mm = s+r(1)

-14 -12 -10

14 -8 -6 -4 -2 0 2 4 6 8 10 12

At days 2, 3, … correction of s-component improves set-up

s=8 (r(1)=0)

r(1)=8 (s=0)

s=4

r(1)=4

s=14

r(1)=-6

systematic and random components unknown, set-up correction on next days = ??
