Boundary conditions of the preliminary candidate selection.

(a) Boundary conditions in coordinates
Region lmin lmax bmin bmax ϖmin ϖmax
s1(+) 285 360 −10 30 5 11
s2(+) 294 300 −20 −10 4 6.5
s3(−) 315 360 −10 0
s4(−) 350 360 −20 10
s5(−) 285 340 25 30
(b) Circular boundary conditions in tangential velocity
v c(vα*) c(vδ) rv
v1(+) −10 −5 17
v2(−) −5 −2.5 10
(c) Rectangular boundary conditions in tangential velocity
v min(vα*) max(vα*) min(vδ) max(vδ) min(v) max(v)
v3(−) −7.5 0 0 15
v4(*) −23 0
v5(*) 0 50

Notes. In panel (b), rv=max((vαc(vα))2+(vδc(vδ))2)$\[r_{v}=\max \left(\sqrt{\left(v_{\alpha *}-c\left(v_{\alpha *}\right)\right)^{2}+\left(v_{\delta}-c\left(v_{\delta}\right)\right)^{2}}\right)\]$. The operation to construct the candidate set from the conditions in the table is (s1s2)(s3s4s5¯)(v1v4v5(v2v3¯))$\[\left(s_{1} \cup s_{2}\right) \cap\left(\overline{s_{3} \cup s_{4} \cup s_{5}}\right) \cap\left(v_{1} \cap v_{4} \cap v_{5} \cap\left(\overline{v_{2} \cup v_{3}}\right)\right)\]$.
