Gemini/Phoenix H-band analysis of the globular cluster AL3
  The globular cluster AL~3 is old and located in the inner bulge. Three
individual stars were observed with the Phoenix spectrograph at the Gemini
South telescope. The wavelength region contains prominent lines of CN, OH, and
CO, allowing the derivation of C, N, and O abundances of cool stars. We aim to
derive C, N, O abundances of three stars in the bulge globular cluster AL3, and
additionally in stars of NGC 6558 and HP1. The spectra of AL3 allows us to
derive the cluster's radial velocity. For AL3, we applied a new code to analyse
its colour-magnitude diagram. Synthetic spectra were computed and compared to
observed spectra for the three clusters. We present a detailed identification
of lines in the spectral region centred at 15555 A, covering the wavelength
range 15525-15590 A. C, N, and O abundances are tentatively derived for the
sample stars.
