Abstract:
Introduction
The calculations involved in determining the flatness of a surface
table from measurements made with instruments such as a block level or
auto collimator can be lengthy, particularly where a large number of
ordinates are taken. A solution to this problem is presented in this
note in the form of an Autocode programme which will cater for up to 100
ordinates.
The datum from which the variations in the flatness of the surface
table are determined is the least squares mean plane. This may be defined
as being that plane which makes the sum of the squares of the errors
relative to it a minimum … [cont.].
