Query: Living life on the edge - Wide-field VLBI at 90 cm!   We report on a recent 90 cm wide-field VLBI survey of two 3.1 deg^2 fields
using the VLBA, Westerbork and Jodrell Bank telescopes. In-beam calibration was
used to calibrate each field, the process was simplified by imaging the
calibrators in DIFMAP and transferring the calibration solutions to AIPS using
the newly developed DIFMAP task - cordump. We detected and imaged 13 out of the
141 sources originally detected by the low resolution (54") WENSS survey of the
same two fields. The sources were detected at 7-12 sigma levels above the image
noise, had total flux densities ranging between 85-1640 mJy and were between
16'-58' from the phase centre of each field. This is the first systematic (and
non-biased), deep, high resolution survey of the low frequency radio sky. These
initial results suggest that new instruments such as LOFAR should detect many
compact radio sources and that plans to extend these arrays to baselines of
several thousand kilometres are warranted.
