Left: amplitude of the variables (p-value ≤5% as closed circles and 5% <p-value ≤ 10% as closed circles with cross) and target photometric uncertainty of the non-varying objects (coloured triangles) across the entire spectral range of the sample. Right: colour−colour diagram of the entire L through T spectral range with the full sample plotted with open circles, showing the colour spread of the targets. The variables from the BAM sample are overplotted (p-value ≤5% as closed circles and 5% <p-value ≤ 10% as closed circles with cross). The L–T transition is indicated by the dashed lines.
