  2. STRATEGY: • Comparison of transmission length measurements and number of hits as a function of the distance for neighboring lines by OB faces, in order to see which line collects the largest amount of signal, probably the candidate to measure, this to reduce the shadowing effect. • Lines 4 and 2 multi-faces runs (f1, f2, f3, f4, f5, f6 respectively): • L2: 52693, 52696, 52698, 52700, 52702, 52704. • L4: 36035, 36041, 36043, 36044, 36045, 36047. • L2 run with large statistics (1M events): 44552. • New consideration to define the minimum and the maximum distance to fit: • Rmin  The storey where Nhits/Nflashes < 0.10 (mean value of the OMs). • Rmax  Rmin + 6 storeys. • Links to all plots in the conclusions section.

  3. SAME FACES DIFFERENT TARGET LINES:L4 MULTI-FACES RUNS

  4. Largest amount of data for f1 on L4. • L1 and L2 seems to collect the same amount of light from 125 m, where the fits normally start. The same is seen for L3 and L6. • L8 and L10 are the more distant lines, transmission length in L8 slightly differ concerning to other target lines. L10 signal is not collected, only noise not well selected as signal is registered (time distributions in next pages).

  12. Largest amount of data for f2 on L2. • L1 and L2 seems to collect the same amount of light from 125 m, where the fits normally start. The same is seen for L3, L6 and L8 (but L is the lowest value among them but compatible with the one for the line which collects the largest amount of data). • L10 is only noise.
