Abstract:
We have carried out the Sino-German 6cm polarisation survey of the
Galactic plane at 6cm in total and polarised intensity using the
Urumqi 25-m telescope of Xinjiang (formerly Urumqi) Astronomical
Observatory, Chinese Academy of Sciences. The angular resolution is
9.5-arcmin. The surveyed area covers 10° to 230° in Galactic
longitude and absolute Galactic latitudes of up to 5°. The
measured rms-noise is about 6.1 mJy/beam area for total intensities
and 3.05mJy/beam area for polarised intensities. The survey maps are
accessible from http://zmtt.bao.ac.cn/6cm/ .
Description:
From the survey maps we derived a catalog of small-diameter sources
by fitting a two-dimensional elliptical Gaussian to them. We list in
table1 total intensity data for 3832 sources with a fitted diameter
smaller than 16 arcmin. We list sources with a peak flux density
exceeding 30mJy. We also identified 125 linearly polarised sources in
the survey maps, which were listed in table2, with a peak polarisation
flux density larger than 10mJy.
