+The flag fs=2 is detected on the observation A(t), the previous value A(t-1) is also flagged fs=2, and the next previous value A(t-2) is flagged fs=1.
-The flag fs=2 is detected on the observation A(t2), the previous value A(t1) is also flagged fs=2, and the next previous value A(t0) is flagged fs=1.
