Description:
The CASPEC echelle spectrograph at the ESO 3.6 m telescope was used to
obtain high resolution spectra of Arp 1145 and Arp 2240, two stars of
the Baade Window, near the globular cluster NGC 6522. From a detailed
analysis using equivalent widths and spectrum synthesis we derive the
stellar parameters (Teff, log g and [M/H])=(4750,1.2,-0.9) and
(5000,2.15,+0.2), respectively for Arp 1145 and Arp 2240.
