Scan #: the name of the STL file and subsequent mesh that was analyzed; Lux: light intensity under which the specific scan was performed measured in lux; Std. Dev.: the standard deviation of all the gap distance values measured in mm; Min.: the smallest gap distance value measured in mm; Max.: the largest gap distance value measured in mm; Avg.: the arithmetic mean of all the gap distances measured in mm.
