CH01; 12.15
CH03; 12.15 Development of grey shade structure within the big dark area
Probable evaluation potential Darkening in Ch03 can be determined quantitatively and automatically Can be used together with the deviation images (difference of motion corrected images) for the life cycle of cells
Further development of convective cells
