  We present the results of determining the coordinates of the vertices of
various stellar systems, the centroids of which are located in the Galactic
plane. To do this, the positions, parallaxes, proper motions, and radial
velocities of red giants and subgiants contained in the $Gaia$~DR3 catalogue
have been used. When determining the components of the deformation velocity
tensors in local coordinate systems, we found the coordinates of the vertices
of the stellar systems under study. It turned out that there is a complex
dependence of vertex deviations $l_{xy}$ in Galactocentric cylindrical ($R,
\theta$) and Galactic rectangular ($X,Y$) coordinates. Based on the approach
proposed in this paper, heliocentric distances to vertices have been determined
for the first time. The results obtained show that in addition to the fact that
the angular coordinates of the Galactic center and the vertices of stellar
systems do not coincide, their heliocentric distances do not coincide as well.
This presumably indicates that there are structures in the Galaxy that
noticeably affect its axisymmetry.
