The selection of WD candidate can be performed by means
of all these parameters.
In any case, spectroscopic follow-up is required in order to
confirm the nature of these candidates.
Object selection criteriaHalo WDs are difficult to identify, due to their faint magnitude (Mv > 15, and the small number of these objects. Anefficient methods is to select:
