In accordance with our investigation on the contours of the constant probability density of the ship-position regarding several typical forms of the chain of the Decca Navigator System, it is found that the fundamental rules in selecting the most accurate pair are as follows: (A) You should utilize the pair except the nearest slave station, the pair on the opposite, when yon, close to the extension of the base line, enter the wedge-shaped part. (B) The borderline for selecting the most accurate pair near the base line is curved into the side which has a greater angle drawn by the two base lines, in case each neighbouring angle is different. (A)' According to the differences of the lane widths on the base line, the wedge-shaped part in the item (A) should be changed as follows: a) wider to each side, when the opposite pair is (P, R) b) narrower from each side, when the opposite pair is (R, G) c) biased towards the (R, G) side, when the opposite pair is (P, G) (B)' According to the differences of the lane widths on the base line, the borderline in the item (B) should be changed as follows, even when the angles drawn by each neighbouring base line are equal. a) much biased towards the (R, G) side, near the base line <MR>^^^ b) fairly biased towards the (P, G) side, near the base line <MP>^^^ c) slightly biased towards the (R, G) side, near the base line <MG>^^^
