Metanolio mazerių MERLIN fotometrija

A sample of the 6.7 GHz methanol maser sources found in the unbiased survey of the Galactic plane taken with the Toruń 32 m dish has been observed using the Mk II -- Ca baseline of MERLIN. The phase-referencing observations resulted in maser positional accuracies of 50 mas in RA and 100 mas in Dec for strong single-peak targets. Preliminary results are presented for the first set of sources. The coordinates of methanol sources are given. Comparison with infrared and radio continuum maps revealed that 7 out of 8 targets are associated with far infrared emission at 60 μ m, while 2 of them show 2.2 μ m emission and are accompanied by ultracompact H II regions seen in the 5 and/or 21 cm continuum.
