caption: Mean line of the profile, m
exif: {"Image DocumentName": "Mean line of the profile, m", "Image ImageDescription": "Mean line of the profile is denoted by m. It is a line with a shape of geometrical profile (perfect geometric line) and it runs parallel to that profile. The mean line of the profile is determined so that the sum of squared deviations from this line is the smallest. ...or otherwise: Surface area above and below the mean line of the profile is the same! z. x. Mean line. . We then start the analysis by determining the mean line of the profile. It has an ideal geometrical shape \u2013 for example it\u2019s perfectly straight or ideally circular. And it is determined so, that the sum of squared deviations from this line is the smallest \u2013 it is the arithmetic mean of the profile. That basically means that if we draw the mean line on the profile, the surface areas below and above this line are the same. The mean line is a starting point for further examination. L = LV.
