stars were classified as irregular if no consistent period could be found. These stars will not be discussed further in this paper.

The variables {#var_section}
=============

Periods have previously been published in the literature for the LPVs V1–V8, V11, V13, V18 and V21 (we use the nomenclature of Clement et al.[@clement01]). Light curves for these stars derived from the current observations are given in Lebzelter et al.([@LWHJF05]), along with some discussion of the origin and reliability of the published periods. These periods are given in column 7 of Table\[variables\]. Beside these stars, a few more red giants have been identified as variables before, namely V15, V16, V17, V19, V20, V22, V23, V25, V27, V28 and A19. For some of these (V15 to V17, V25 and V28) periods were given by Fox ([@fox82]). A19 was reported variable by Lloyd-Evans ([@LE74]), but no period was given. Later variability surveys, like those of Kaluzny et al.([@kaluzny98]) and Weldrake et al. ([@weldrake04]), have focused on binaries and RRLyr stars and thus typically were not suitable for determining periods of the stars on the upper giant branch due to overexposure. The long period variables they report are most likely members of the Small Magellanic Cloud.
