  In the framework of the Glauber approach we investigate the influence of the
initial fluctuations on various measures of the initial-state geometry in
63Cu+197Au and 238U+238U relativistic ion collisions. Comparing variants of
Glauber model (the wounded-nucleon model, the mixed model, and the hot-spot
model) we indicate sensitivity of certain observables, in particular for the
azimuthal eccentricity parameters as well as for the correlation of directions
of the principal axes associated with the Fourier components. We apply
GLISSANDO in our analysis.
