Spectra of four selected lines (CI 5380.3 Å, MnI 5394.7 Å, FeI 5930.2 Å and SiI 5948.5 Å) have been obtained in the quiet photosphere, at regular intervals along the polar axis and the equator. The spatially averaged spectra have been analysed, studying the centre-to-limb variation and possible changes with heliographic latitude of the residual

The Two Micron Galactic Survey (TMGS) is the most sensitive near-infrared large scale survey of the Galactic plane yet attempted. The TMGS has so far covered some 2552 square degrees of sky to a limiting magnitude of mk ≍ +10 and detected some 470000 sources. The majority of these are in the Galactic plane and have no known visible counterparts
