Fig. 2
First moment map toward the northern portion of the M 31 HI gas distribution. Displayed are radial velocities in the range −588 ≤ vLSR [ km s-1 ] ≤ −110. Here, the confusion of M 31 HI gas with that of HVC complex H is most severe. This first moment map allows HI gas superimposed on a single line of sight but moving at different radial velocities to be disentangled.
