Radio observations for seven NUGA sources. a NGC 4579 was
excluded since MERLIN observations were already carried out; the data
are taken from the MERLIN archive. b NGC 3147 and NGC 4579 were not
observed because VLBA data were already available from Ulvestad & Ho
(2001). c The first observations in 2002 were not successful due to
technical problems with some of the antennas and were thus repeated in
2003; the results of both observations are consistent with each other
but only the 2003 data sets are used for further discussion due to the
higher quality of the data. d Eb Effelsberg,

Radio positions of the seven NUGA sources, mainly derived
from the EVN 6 cm (core) or MERLIN 18 cm/6 cm (jet) observations by
fitting Gaussian profiles to the emission (the positions are
coincident within the uncertainties of the different
observations). The positional uncertainties are estimated from the
Gaussian fits and also include the most recent (i.e., determined in
the past 4 years) astromectric errors of the used

include the calibration uncertainties of 5-10% and represent only
the statistical uncertainties of the fit. The given angles are
