I also noticed that SNSMO in VLMB mode *introduces* R-L phase differences even when there are none in the original SN table, which doesn't seem right.  See the attached TASAV, on which:

SN1 = original, no R-L differences in phase
SN2 = SNSMO 31DEC14, 'VLBI' - no R-L differences in phase
SN3 = SNSMO 31DEC14, 'VLMB' - R-L phase difference introduced
SN4 = SNSMO 31DEC12, 'VLMB' - R-L phase difference introduced

SNSMO parameters  

DOBWTEE  0
SAMPTY 'GAUS'
DOBLANK 0; CUTOFF 0; REFANT 7
BPARM     0,0,3,3,3,0,0,1,1,1
