Abstract :
We have combined recent radial velocity measurements of Fekel et al. (2000) with previously studied older ones, to test for the continued presence of the second period, found by G?lis et al. (1999), which could be due to pulsations of the cool component of the AG Dra binary system. Fekelʹs data, even taken by themselves, also marginally suggest the presence of variations near the previously found second period. The period is in any case clearly seen, when all radial velocity measurements are combined.
