Abstract:
We present new continuum VLA observations of the nearby Sy 1.5 galaxy
NGC 5033, made at 4.9- and 8.4-GHz on 2003 April 8. Combined with VLA
archival observations at 1.4- and 4.9-GHz made on 1993 August 7, 1999
August 29 and 1999 October 31, we sample the galaxy radio emission at
scales ranging from the nuclear regions (<100pc) to the outer regions
of the disc (∼40kpc). The high-resolution VLA images show a corejet
structure for the Sy 1.5 nucleus.
Description:
We reanalysed archival VLA data on NGC 5033 obtained under programme
AU0079 on 1999 August 29 (1.4GHz, A configuration) and 1999 October 31
(4.9GHz, B configuration), respectively. These data sets provide very
similar angular resolution, since the increase in angular resolution
from 1.4 to 4.9GHz is essentially compensated by a decrease in the
longest antenna separation, which is approximately a factor of 3
between the A and B configurations of the VLA.

Note on table2.dat: Background sources of the 1.4-GHz NGC 5033 field, from
VLA observations obtained on 1993 August 7 with the VLA-C. We used the
AIPS task SAD to search for point-like sources above a flux density
level cut-off of five times the off-source (1rms=93uJy/beam).
