Using CED to verify the angle and wire correlation,

Zooming in on the view paralell to the direction of the wires in ced, we can examine the wire corresponding theta angle in the drift chamber.

Table 1: Superlayer 1 Wire 1 Coordinates
Coordinates(cm)	Layer 1	Layer 2	Layer 3	Layer 4	Layer 5	Layer 6
x	20.42	21.51	21.39	22.49	22.37	23.47
y	0.00	0.00	0.00	0.00	0.00	0.00
z	243.41	244.18	245.51	246.28	247.62	248.38

Table 2: Superlayer 1 Wire 2 Coordinates
Coordinates(cm)	Layer 1	Layer 2	Layer 3	Layer 4	Layer 5	Layer 6
x	21.64	22.73	22.61	23.71	23.58	24.69
y	0.00	0.00	0.00	0.00	0.00	0.00
z	242.86	243.62	244.94	245.71	247.05	247.81

Corresponding theta angles can be found for other wires, in Region 1, Superlayers 1 and 2.
