The work was undertaken in preparation of orbit and spin modeling for future polarized proton and helion runs at RHIC. The investigations include re-computation of 3-D OPERA field maps of the helical snakes and particle and spin tracking. There is a series of sub-products of this study, amongst others, the appropriate settings of the AGS cold snake when changing its strength, cold snake settings for polarized helion programs, non-linear coupling in the AGS, the transport of the stable polarization axis from the AGS to RHIC injection kickers, and in addition, a series of high accuracy 3-D field maps have been produced, in view of long-term tracking in the AGS for beam and polarization transmission studies.
