Abstract: We present CLEAN time-series analysis of synthetic line profiles obtained from a non-radially pulsating stellar model which incorporates effects of rotation. Two models (a low-degree l = 2, m = -1; and a high-degree l = -m - 8) were calculated for a rapidly rotating late 0-type star, where the prograde oscillation frequency in the corotating frame of the star is twice that of the stellar rotation frequency. An interpretation of the results based upon the usual slow-rotation assumptions gives a mis-identification of both period and mode of oscillation for the low-degree model, but correctly identifies the NRP characteristics of the sectorial model. The misidentification of the low-degree model has possible implications for previous mode identifications, and we urge caution when analysing the line profile variations of rapidly-rotating, non-radially pulsating stars.
