Sample no.	Direction of the tube	diameter of the tube (mm)	Relation between adjacent loops	Maximum interval between adjacent loops (mm)	Length of the tube (mm)
S1	H		Parallel	45	9000
S2	H		Not parallel	45	13000
S3	H		Not parallel	40	15000
S4	V		Not parallel	45	13000
S5	V/H (front/back)	(front); (back)	Not parallel (front); Not parallel (back)	45 (front); 40 (back)	14000

Note: “H” means horizontal, and “V” means vertical.
