VizieR Online Data Catalog: K magnitudes of OB stars in UCHIIs (Bik+, 2005)

K-band spectra were taken of point sources in 31 regions from the sample of 44 IRAS sources with UCHII colours presented in Kaper et al. (2005, A&A, submitted). The point sources were selected based on their position in the colour-magnitude diagram. The brightest and most reddened sources were selected for follow-up spectroscopy.

Medium-resolution, long-slit (120") K-band spectra were obtained with ISAAC mounted on Antu (UT1) of ESO's Very Large Telescope (VLT), Paranal, Chile.

The observations were carried out during a visitor mode run (by LK and MMH) on March 18-20, 2000, and a service mode run in the period between May 18 and July 16, 2000.
