Overview
Asteroseismology: need for accurate mode identification
Introduction to pulsational line-profile variability
Confirming pulsational nature of line-profile variability: Doppler Imaging
Mode identification: Moment Method
Mode identification: Amplitude and phase diagrams across the line profile
Accuracy of spectroscopic mode-identification
Example of pulsation-mode identification: the subdwarf-B star Balloon090100001
