  We present the Fabry-Perot observations obtained for a new set of 108
galaxies that completes the GHASP survey (Gassendi HAlpha survey of SPirals).
The GHASP survey consists of 3D Ha data cubes for 203 spiral and irregular
galaxies, covering a large range in morphological types and absolute
magnitudes, for kinematics analysis. The GHASP sample is by now the largest
sample of Fabry-Perot data ever published. We have derived Ha data cubes from
which are computed Ha maps, radial velocity fields as well as residual velocity
fields, position-velocity diagrams, rotation curves and the kinematical
parameters for almost all galaxies. Original improvements in the determination
of the kinematical parameters, rotation curves and their uncertainties have
been implemented in the reduction procedure. This new method is based on the
whole 2D velocity field and on the power spectrum of the residual velocity
fieldrather than the classical method using successive crowns in the velocity
field. Among the results, we point out that morphological position angles have
systematically higher uncertainties than kinematical ones, especially for
galaxies with low inclination. Morphological inclination of galaxies having no
robust determination of their morphological position angle cannot be
constrained correctly. Galaxies with high inclination show a better agreement
between their kinematical inclination and their morphological inclination
computed assuming a thin disk. The consistency of the velocity amplitude of our
rotation curves have been checked using the Tully-Fisher relationship. Our data
are in good agreement with previous determinations found in the literature.
Nevertheless, galaxies with low inclination have statistically higher
velocities than expected and fast rotators are less luminous than expected.
