Notes. 

(a)

Velocity range used for integration: –20 km s-1 to 30 km s-1.

(b)

Blue emission is calculated by selecting a velocity range of –20 to 2.7 km s-1.

(c)

Red emission is calculated by selecting a velocity range of 10.5 to 30 km s-1.

(d)

In 0.5 km s-1 bins.

(e)

Upper limits are 3σ.

(f)

In 1.0 km s-1 bins.
