Next: The stage and Up: The ESO Red Sky Previous: Artefacts . Fig. 3 shows the distribution of stars. The most striking feature is the rapid steepening of the density gradient towards the Milky Way region at the right and left hand edges of the total field, apparent from the dramatic change in colour in this false colour presentation. Noticable changes in star density across even short distances are indicated by colour changes within individual plates. ... Fig. ...

... The distribution of galactic RCB stars is controversial. Several authors have argued that they belong to a thick galactic disk, and are thus old Population I stars. ... However, their distribution and space velocities suggest they may alternatively belong to the even older galactic bulge (Population II, [ Drilling 1986 ]). ... These are the only RCB stars for which a distance is known and hence for which an absolute magnitude can be deduced. ...
