Abstract
During the PEP-II LER commissioning run in July 1998 the beam profile in the tune up dump profile monitor just before LER injection showed an anomalous parabolic shape. The sextupole component of the field of bend magnets B2 and B4 in the beginning of the south injection tunnel (SIT) was thought to be the cause of this. An off-line model of the B2/B4 bend magnet field was created using DIMAD. Results of particle tracking simulated in DIMAD were compared with on-line lattice diagnostic data and observations of the beam profile on the tune up dump screen
