Description:
The Westerbork Nortern Sky Survey (WENSS) is a low-frequency (325 MHz)
radio survey that will cover the whole sky north of a declination of
30 degrees A first installment of the survey covers an area of 570
square degrees around the North Ecliptic Pole. A source list
comprising 11,299 sources and 994 components is listed in Table 6 of
the paper. This table is presented here.

Note (1): Uppercase letters designate components.
Lowercase letters were added in May 1999 to remove the
name collisions. These concern 118 WNB names assigned
to 237 sources.
Note (2): S = Single component source
M = Multiple component source
C = Individual component
E = extended source
Note (3): If the source is unresolved then a value of 0 is assigned to these
parameters
