 There are additional markings 300 mm long and perpendicular to the back line that denote distances of 10 m and 5 m from each goal post . These are relevant at a penalty corner ; the former is the mark from which the attacking team takes the penalty corner and the latter is the closest position which a defender may stand . These marks had been 5 and 10 yards ( 4 @.@ 6 and 9 @.@ 1 m ) in earlier versions of the rules . There is a similar mark 5 m from along the side line ( from where long corners were formally taken ) and a mark 14 @.@ 6 m along the side line indicating the level of the top of the penalty circle . There are also 150 mm long markings where the goal posts are situated .
