Comparison between the highest amplitude Gaia and TESS frequencies for the 215 stars with significant TESS frequencies. Top: Dominant TESS frequency f_TESS against the Gaia derived frequency f_Gaia. The black symbols indicate stars for which we found a match in frequency, the blue symbols show stars matching a frequency other than the dominant signal, and the red symbols indicate the seven stars for which the Gaia frequency does not match any frequency in the TESS data. The lines connect the offset frequencies to the matched counterpart. For three stars the main frequency is below the plotting range. Bottom: Difference between the Gaia and TESS frequencies. The black dashed line indicates our chosen threshold for matching signals (Δf<0.006 d⁻¹).
