Notes. nvar is the total number of variables per class found in all OCs, ncl the number of OCs in which they occur, and ncontour is the number of variable stars in each CaMD contour region identified in Fig. 1. Within these contours, ℱvar is the fraction of stars that correspond to this variable class. Brackets (e.g., ⟨mG⟩) denote average values derived within the contours shown in Fig. 1; values separated by a comma denote ranges. mG and σmG denote the G−band apparent (mean) magnitude and its uncertainty, respectively. Script Letters 𝒜 and 𝒫 denote trimmed G−band amplitude (trimmed_range_mag_g_fov) and Gaia variability period, respectively. Periods are taken from SOS results when available.
Periods taken from the GDR3 SOS main sequence oscillators analysis Gaia Collaboration (2023a)
