Amplitudes and timescales of the granulation-like signature observed in main-sequence stars using NIRISS/SOSS. The TOI 700 results are from this work, while LHS 1140 was studied in C. Cadieux et al. (2024), LTT 9779 was studied in L.-P. Coulombe et al. (2025), and WASP 121 was studied in J. Splinter et al. (2025). Although the sample size is small, the data suggest a trend of σ_gran and τ_gran increasing with stellar mass. The equation of the best-fit line is provided on each plot.
