Abstract:
18 days of MERLIN data and 42h of A-array VLA data at 1.4GHz have
been combined to image a 10-arcmin field centred on the Hubble Deep
Field (HDF). This area also includes the Hubble Flanking Fields (HFF).
A complete sample of 92 radio sources with S1.4>40µJy was detected
using the VLA data alone and then imaged with the MERLIN+VLA
combination. The combined images offer (i) higher angular resolution
(synthesized beams of diameter 0.2-0.5arcsec), (ii) improved
astrometric accuracy, and (iii) improved sensitivity compared with
VLA-only data.
Description:
We observed an area centred on the HDF and located at RA=12:36:49.4,
DE=+62:12:58.00 (J2000) with the VLA in A-array for a total of 50h at
1.4GHz.
We observed the same position with the Multi-Element Radio-Linked
Interferometer Network (MERLIN) at 1.4GHz in 1996 February and 1997
April for a total of 18.23d.
