A new size-independent indicator of scientific publication prestige, the SJR2 indicator, is proposed. This indicator takes into account not only the prestige of the citing scientific publication but also its closeness to the cited journal using the cosine of the angle between the vectors of the two publications' citation profiles. To eliminate the size effect, the accumulated prestige is divided by the fraction of the publication's citable papers, 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 better distributed than the JIF by Subject Area and almost as well distributed 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.
