This paper is a continuation of the rotational velocity study of A-type stars, initiated in Royer et al. (2002, hereafter Paper I). The main goals and motivations are described in the previous paper. The sample of A-type stars described and analyzed in this work is the counterpart of the one in Paper I, in the northern hemisphere.
In short, it is intended to produce a homogeneous sample of measurements of
projected rotational velocities (
)
for the spectral interval of A-type stars, and this without using any
preset calibration.
This article is structured in a way identical to the precedent, except for
an additional section (Sect. 5) where data from this paper, the previous one and the catalogue of
Abt & Morrell (1995) are gathered, and the total sample is discussed in statistical terms.
