[en] This note studies the dependence of the dynamic aperture on the choice of the operating tune ν_x, ν_y in RHIC. Tracking studies for 1000 turns were done over the tune range ν_x ≅ ν_y = 28 to ν_x ≅ ν_y = 29.5. It was found that in each tune interval Δν = 0.5, e.g. ν = 28.5 to ν = 29, the dynamic aperture as a function of the tune has 5 peaks, each of which is a possible operating point. Each of these possible operating points is in a tune region free of imperfection resonances of tenth order or less, and the width of this tune region ranges from Δν = 0.022 to Δν = 0.036. Operating tunes near integer values of ν, which appear desirable because of the relatively large tune interval free of imperfection resonances of 10th order or less, may not be desirable because of the lower dynamic aperture in this region. Operating near integer tunes may not be desirable for heavy ions like Au, but may be desirable for the lighter ions which do not experience a large transverse growth due to intrabeam scattering. If a loss in dynamic aperture of 2 mm is regarded as significant, then the tune range of ν = 28 to ν = 28.5 does not appear as attractive as the tune range ν = 28.5 to ν = 29.5
