	Sample: sample ID related to the denomination in the paper Part 2.
	ID: Id of each grain
	Mobility: Mobility status ( here "surface")
	Baxis_mm: Estimated Intermediate axis measured over polygones in mm
	Area_mm2: Area of the polygones in mm²
	Layer: Indicate from which layer are comming the detected grain (Pre or Post event layer)
	
2_Dynamic:
For each procedure (Control, Manual, Automated, Reviewed), these data represent all the grains identified as Mobile or Immobile.
