1.	Karlsson, Roland, 1948-, et al. (author) The 18 cm OH distribution in the Galactic Center Torus 1987 In: AIP Conference Proceedings. - New York : American Institute of Physics (AIP). - 0094-243X. Conference paper (other academic/artistic)abstract The 18‐cm OH distribution in the Galactic Center region near Sgr A has been studied in all four of the 1612, 1665, 1667 and 1720 MHz OH lines using the VLA with 4 arcsec angular resolution and 9 km s− 1 velocity resolution. Three 1667 MHz OH spectral line absorption maps, at +51, +25 and −1 km s− 1, covering a 4’.3×4’.3 region around Sgr A are presented together with an 18‐cm continuum map. In addition, a complete set of velocity maps from +139 to −159 km s− 1, covering a 3’×3’ region around the Galactic Center nuclear torus, is presented. Absorption by the +50 and +20 km s− 1 molecular cloud belt is seen towards Sgr A East, but not towards Sgr A West. Absorption is also seen towards Sgr A* in the velocity ranges of +43 to −36 km s− 1 and −142 to −151 km s− 1. The Northeast and Southwest torus components can be traced out to velocities of +139 and −151 km s− 1. A ‘‘Northwest’’ feature, starting northwest of the Western continuum arc, appears faintly at a velocity of +51 km s− 1 and then migrates slightly southward until it merges with another feature at a velocity of +78 km s− 1. This other feature ‘‘Sweeps’’ in towards Sgr A* as the velocity decreases from +78 to +16 km s− 1.

5.	van Genderen, A. M., et al. (author) VBLUW photometry of the association Sco OB1 (containing the open cluster NGC 6231). A discussion on the evolutionary status of the hypergiant zeta 1 Sco (B1 Ia +) 1984 In: Astronomy and Astrophysics Supplement Series. - 0365-0138 .- 1286-4846. ; 58:3, s. 537-548548 Journal article (peer-reviewed)abstract VBLUW photometry of nearly 190 stars in the very young association Sco OB1, including the cluster NGC 6231, is presented and discussed. Temperature and surface gravity are determined with the aid of theoretical colours. Individual reddenings are also obtained. The distance modulus ( m- M) 0=11.00plusmn0.25 is similar to the value found by Shobbrook (1983). It appears that the reddening is not uniformly distributed across the association (~2degtimes1deg), but that areas of low and high reddening, varying from E( B- V) J=0.35 up to 0.67, can be distinguished. Practically all reddening is caused by dust in the local spiral arm up to a distance of at most 700 pc from the Sun. The Sagittarius-Carina arm where Sco OB1 is situated is practically transparent over a distance of ~0.5 kpc. The kinematical age of ~10 6 yr is in reasonable agreement with the average evolutionary age of ~(3.6plusmn0.6)times10 6 yr of the 12 brightest stars. The evolutionary status of the hypergiant zeta 1 Sco (B1 Ia +) is discussed

Accurate coordinates are given.
