which two layer-lines (LL) were used?
Note, there may be multiple acceptable answers to this question. Format: LL (R, Z)
LL (17, 97)
LL (157, 87)
What are the possible Bessel order ranges for those two vectors?
LL (17, 97):
2*π*R*rmax = 2 * 3.14 * (17/4096/1.08) * 152 = 3.67 Bessel order n ≤ 2
2*π*R*rmin = 2 * 3.14 * (17/4096/1.08) * 75 = 1.81 Bessel order n ≥ 1
LL (157, 87):
2*π*R*rmax = 2 * 3.14 * (157/4096/1.08) * 152 = 33.9 Bessel order n ≤ 32
2*π*R*rmin = 2 * 3.14 * (157/4096/1.08) * 75 = 16.7 Bessel order n ≥ 18
