  1. Field evaluation: Short runs Objects of interest: Classical pulsators with periods lower than ~a few days For a mV=9: noise level in 20 days ~ 1.4ppm (gain ~100/current ground-based on same duration) d Scuti, g Dor,B Ceph, Be, … Potential classical puls.: O,B,A, early F stars with mV<9.5 Potential Solar-like puls.: Red giants (cf de Ridder CW8) Late A and F stars with mV<7.5-8. (objects with this magnitude usually satisfy criterion 0, i.e. a S/N>=1 expected for a significant number of peaks ( cf Samadi CW6), ‘no precision on frequency guaranteed, but interesting for amplitudes.)
