images of radio source J0700+22. 20cm
and 6cm observations were taken on 22
December 1997 during the D-configuration.
The 4cm image presented occurred during
the D->A configuration (only the inner 18
antennas remaining in their D-configuaration
positions were used). Images from the Digital
Sky Survey (DSS) show an elliptical galaxy at
ra=7h0m37.6s dec=+22d29'41.58" which corresponds
to J0700+22's radio core.
L-band (1.4 GHz/21cm)
VLA D-configuration, observed 22 Dec 1997
Synthesized beamwidth = 44.0"
Peak flux density of Core = 59.5 mJy
Peak flux density of NW component = 73.2 mJy
Peak flux density of SW component = 46.7 mJy
Noise level: 1.1 mJy/beam
C-band (4.9 GHz/6cm)
High noise level due to snow and ice in the VLA
dishes and subsequent high system temperatures.
VLA D-configuration, observed 22 Dec 1997
Synthesized beamwidth = 14.0"
Peak flux density of Core = 20.4mJy
Peak flux density of NW component = 6.5 mJy
Peak flux density of SW component = 3.0 mJy
Noise level: 0.163 mJy/beam (approx. 3x normal)
Core exhibits relatively flat spectrum (in comparison to
outer-lying components); only factor of three between 6cm
& 21cm peak flux dens.
X-band (8.4GHz/3.6cm)
18 antennas in VLA D-configuration, observed 12 Feb 1998
(Synthesized beamwidth = ~8.4")
Peak flux density of Core = 14.4mJy
Peak flux density of NW component = 0.29 mJy
Peak flux density of SW component = 0.51 mJy
Noise level: 0.12 mJy/beam
