can be inferred. The plume in front of both limbs, that is, plume 6 could be associated with a very faint bright point. Plume 7 presents a nice example of the importance of having 3D information when associating plumes with bright points. If we consider only EUVI B, then plume 7 seems to be related to a bright point right in front of the limb. However, when we check both Figures \[fig:side\_view\] and \[fig:top\_view\] we find this plume is rooted just behind the limbs seen by EUVI A and B. Therefore, the association to the bright point near the limb is probably spurious. For plumes 8 and 9, it is difficult to reach a firm conclusion. We see two bright points in both images close to the plume roots. The association is possible if the bright point relevant to plume 8 is big enough and the height of the bright point relevant to plume 9 is large enough that it could be seen from EUVI A and B, even though it is behind the limb.
