Abstract:
During 2010-11, the Medicina 32-m dish hosted the seven-feed
18-26.5GHz receiver built for the Sardinia Radio Telescope, with the
goal to perform its commissioning. This opportunity was exploited to
carry out a pilot survey at 20GHz over the area for
δ>+72.3°. This paper describes all the phases of the
observations, as they were performed using new hardware and software
facilities. The map-making and source extraction procedures are
illustrated. A customized data reduction tool was used during the
follow-up phase, which produced a list of 73 confirmed sources down to
a flux density of 115mJy. The resulting catalogue, presented here, is
complete above 200mJy. Source counts are in agreement with those
provided by the Australia Telescope 20GHz (AT20G) survey. This pilot
activity paves the way for a larger project, the K-band Northern
Wide Survey (KNoWS), whose final aim is to survey the whole Northern
hemisphere down to a flux limit of 50mJy (5σ).
Description:
In 2010 winter, we produced a total intensity test map covering the
Northern polar cap (∼880deg2, δ>72.3°), which allowed us to
deeply check the new hardware and software facilities - the MF, the
analogue continuum backend and the telescope control system - which
is a new system based on the ALMA Common Software. The actually chosen
band is 20-22GHz.
