This table describes the main-sequence oscillators.

Columns description:

solution_id : Solution Identifier (long)

All Gaia data processed by the Data Processing and Analysis Consortium comes tagged with a solution identifier. This is a numeric field attached to each table row that can be used to unequivocally identify the version of all the subsystems that were used in the generation of the data as well as the input data used. It is mainly for internal DPAC use but is included in the published data releases to enable end users to examine the provenance of processed data products. To decode a given solution ID visit https://gaia.esac.esa.int/decoder/solnDecoder.jsp

source_id : Unique source identifier (long)

A unique single numerical identifier of the source obtained from gaia_source (for a detailed description see gaia_source.source_id).

frequency1 : Best frequency (double, Frequency[day${}^{-1}$])

Best frequency corresponding to the highest peak in the frequencygramme.

fap_g_freq1 : False alarm probability corresponding to the best frequency (float, Dimensionless[percentage/100])

False alarm probability corresponding to the best frequency.

amplitude_g_freq1 : Half peak-to-peak amplitude in the G band of the best frequency (float, Magnitude[mag])

Half peak-to-peak amplitude in the $G$ band of the best frequency, referred to as $A_{G,1}$.

phase_g_freq1 : Phase of the oscillation in the G band corresponding to best frequency (float, Angle[rad])

Phase of the oscillation in the $G$ band corresponding to the best frequency, referred to as ${\varphi }_{G,1}$.

num_harmonics : Number of significant harmonics of the best frequency (byte)

Number of significant harmonics of the best frequency.
