Wavelength dependence of two-epoch magnitude differences for the 110 day timescale variable candidates. Gray curves show Δmλ across the 16 medium-band filters. Colored curves highlight the highly variable subset, selected by requiring ∣Δmλ∣ > 0.5 mag in at least 70% of the valid filters (with Nvalid ≥ 9). The dashed line marks Δmλ = 0, where negative values indicate that the source was brighter on 2024 March 24, than on March 23.
