cds-question@unistra.frspectroscopygiant-starsinfrared-photometryvisible-astronomybroad-band-photometrymetallicityWe present first results from a spectroscopic survey designed to examine the metallicity and kinematics of individual red giant branch stars in the outer halo of the Andromeda spiral galaxy (M31). This study is based on multislit spectroscopy with the Keck II 10m telescope and Low Resolution Imaging Spectrograph of the Ca II near-infrared triplet in 99 M31 halo candidates in a field at R=19kpc on the southeast minor axis with brightnesses from 20<I<22.2002AJ....124..234Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/124/234CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/96/1884 : BVRJHK photometry of M31 red supergiants (Humphreys+ 1988)J/AJ/109/2480 : VI photometry of late-type stars in M31.
