[SBS_sim] Replay with fewer planes

[Ole Hansen]

Hi all,

Bogdan asked for replay results with fewer planes.  Here are the numbers 
for the g11 production (1/10 background):

6 planes:   64.4%   (ampcorr_maxmiss = 4, 3d_maxmiss = 4, maxmiss = 3)
5 planes:   67.6%   (ampcorr_maxmiss = 3, 3d_maxmiss = 3, maxmiss = 2)
4 planes:   65.6%   (ampcorr_maxmiss = 2, 3d_maxmiss = 2, maxmiss = 2)

(maxmiss = 1 gives an almost identical results in the case of 4 planes)
