... The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be stars. The results confirm the tendency of early Be stars to be surrounded by dense clusters of lower mass "companions", while Ae stars are never found to be associated with conspicuous groups. ... Only the most massive stars (10-20Msun) are found to be associated with dense (10^3 pc^-3) stellar clusters. ...

In March of 2001, a routine analysis of FR533N VISFLAT images revealed an anomaly: the filter wheel appeared to be offset by about 0.42 in some images. ... This document describes a more exhaustive analysis of the filter wheel rotation anomaly: flatfield images for all available filters in the archive were inspected to determine if they exhibited similar behavior. ...

... The DAL is essentially implemented in C++. The design takes the form of a set of abstract classes which provides the fundamental DAL interface. There are currently two implementations (both in C++) of this abstract interface; one is the High Memory Model and the other is the HighLow Memory Model. ... In particular, an understanding of the C++ class hierarchy will lead to more generic algorithms e.g. use BlockT rather than ArrayT if only the BlockT methods are needed. Class Hierarchy . ...

... The metal abundance gradient in the disk of the Galaxy is found from stars with abundance determination from detailed analysis: d[Fe/H]/dR=(-0.05?0.01) kpc -1 . It is shown that the gradient can be explained by the fact that the disk is constituted of two metallicity groups of stars with an abundance jump between the groups. ...

... Comparative study of Tl-2201 single crystals with T c =30 and 110 K by means of X-ray structural analysis and NMR. Abstract: . The crystal structure of a tetragonal single crystal of Tl-2201 with T c =30 K has been determined by the X-ray diffraction technique ( a = 3.8717(3), c = 23.224(3) Angstrom, space group I4/mmm, Z = 2). The chemical composition is found to be Tl 1.90(1) Cu 0.10(1) Ba 2 CuO 6.18(4) . ... Structural parameters of Tl-2201 cuprates with various T c have been compared. ...
