Artificial K-band photometric images of remnant gSdgSdo51 (E/S0), for the face-on and edge-on views defined on the basis of the total stellar angular momentum (see Sect. 3.1). The remnant contains a high-rotating embedded disc, very inclined with respect to the main outer disc, which dominates the total stellar spin of the galaxy. This is biasing the “face-on view” towards a face-on view of this embedded inner disc, instead of a face-on view of the outer disc. The field of view in all panels corresponds to 50 kpc×50 kpc. The arrows indicate a physical length of 5 kpc. (A colour version is available in the electronic edition.)
