Notes. Each modulation is modeled as fi = Aicos[2π(νit + ϕi)], where Ai, νi, and ϕi is the given amplitude, frequency, and phase, respectively. The phase is relative to a starting time TS = 2458325.297922 BJD.

( * )Frequencies interpreted as independent pulsation modes and used for the detailed asteroseismic analysis.

( † )Evaluated from a specific Monte-Carlo test as described in Zong et al. (2016b).

( ‡ )These signals are difficult to interpret. Instrumental artifacts of yet unclear origin may be present in this frequency range and contamination from a bright nearby object, TIC 278659026 (TYC 9327-275-1), cannot be excluded.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
