a Sectors defined on the log cross-section for preclassification of the sample boards according to expected direction of annual rings. The sectors are centred on the pith and aligned with the sawing pattern so that the centre line of sector is parallel to the cutting lines of the first saw. For sideboards, the 1 scheme is rotated 90°. The diameter of the circular third sector equals the width of the boards from the centre cant. b CT slice image of a log with reconstructed sawing pattern displayed in the CT image processing software used. The sector scheme is not shown in the user interface
