Identify the non-zonal components of TIC 458263480’s rotational multiplet

Determine which observed pulsation frequencies constitute the non-zonal components of the rotationally split multiplet in TIC 458263480 and thereby establish its rotational interpretation.

Background

The paper identifies a seemingly clear zonal mode in TIC 458263480 but finds multiple plausible neighboring frequencies that could serve as its prograde and retrograde components. The selected components satisfy the adopted asymmetry and splitting criteria, while higher-amplitude alternatives are excluded by the tolerance threshold. Resolving which frequencies belong to the multiplet is necessary for a secure determination of the star’s rotational frequency and mode identification.
