  In the framework of the circular restricted three body problem we show that
the numerically computed strength SR(e,i,w) is a good indicator of the strength
and width of the mean-motion resonances in the full space (e,i,w). We present a
survey of strengths in the space (e,i) for typical interior and exterior
resonances. The resonance strength is highly dependent on (e,i,w) except for
exterior resonances of the type 1:k for which the dependence with (i,w) is
softer. Such resonances are thus strong even for retrograde orbits. All other
resonances are weaker at very-high eccentricities for w ~ 90 or 270 and 60 < i
< 120. We explore the resonance structure in the space (a,i) by means of
dynamical maps and we find structures similar to those of space (a,e).
