  A new size-independent indicator of scientific journal prestige, the SJR2
indicator, is proposed. This indicator takes into account not only the prestige
of the citing scientific journal but also its closeness to the cited journal
using the cosine of the angle between the vectors of the two journals'
cocitation profiles. To eliminate the size effect, the accumulated prestige is
divided by the fraction of the journal's citable documents, thus eliminating
the decreasing tendency of this type of indicator and giving meaning to the
scores. Its method of computation is described, and the results of its
implementation on the Scopus 2008 dataset is compared with those of an ad hoc
Journal Impact Factor, JIF(3y), and SNIP, the comparison being made both
overall and within specific scientific areas. All three, the SJR2 indicator,
the SNIP indicator and the JIF distributions, were found to fit well to a
logarithmic law. Although the three metrics were strongly correlated, there
were major changes in rank. In addition, the SJR2 was distributed more
equalized than the JIF by Subject Area and almost as equalized as the SNIP, and
better than both at the lower level of Specific Subject Areas. The
incorporation of the cosine increased the values of the flows of prestige
between thematically close journals.
