Whole frame condition against vibrational amplitude.

Only the three colonies from Fig 2 are considered here (Colony No. 2 is represented by red squares, No. 5 by black circles, and No. 6 by blue triangles), at seven points in time when the frames condition were assessed visually. When colonies are considered individually, the linear combination of frame condition can be correlated to the extracted vibrational signal but the multiplying factors (α, β and δ) are not the same for each frame (red (α, β, δ) = (0.414,0.147,-0.668)x10-7, black (α, β, δ) = (0.402,-0.109,0.441)x10-7, blue (α, β, δ) = (-0.439,0.0006,0.68)x10-7).
