Fig. 1. Image of the three echelle cuts toward LMC 2. The zero-point in the spatial direction for each echellogram is
(a) α₂₀₀₀ = 5^h 42^m 10^s; δ₂₀₀₀ = -69° 13' 28",
(b) α₂₀₀₀ = 5^h 45^m 33^s; δ₂₀₀₀ = -69° 25' 05", and
(c) α₂₀₀₀ = 5^h 43^m 04^s; δ₂₀₀₀ = -69° 36' 05".
The velocity zero-points is taken to be the geocoronal Halpha line
