| Abstract: |
A study of the period-amplitude relation for RR Lyrae variables in the globularclusters 47 Tucanae, NGC 6441 and M55 confirms a recent finding that the period-amplitude relation for RRab stars with `normal' light curves is not a function of metal abundance. Evolutionary effects are more important. |
