\caption{\label{summary}An overview of the orbital classification, i.e. apparently single star ("single''), suspected binary ("suspect''), single-lined spectroscopic binary ("SB1''), and double-lined spectroscopic binary ("SB2''), and variability classification of the objects discussed in this paper.
The stars in {\it italics} will be the subject of dedicated future studies.

$^1$ bf \dsct\ star; 
$^2$ shows no cross-correlation profile variations but was classified as a bf \gdor\ star before;  
$^3$ ellipsoidal variability instead of pulsation cannot be ruled out; 
$^4$ shows cross-correlation profile variations, but was classified as a chemically peculiar star before.
