Description:
The three tables contain the 669 Ultra Steep Spectrum sources from the
3 samples WN (WENSS-NVSS), TN (TEXAS-NVSS) and MP (MRC-PMN) (tables
A.1, A.2 and A.3). For each source, the radio fluxes from the surveys
and from VLA or ATCA observations are given, as well as coordinates,
radio structure, angular size and position angle determined from the
radio map indicated in the last column.

Note on fitfiles.dat:
The set of FITS files includes also the sources observed with the VLA,
but not included in the final list of 669 sources due to revisions of
the NVSS catalogue. These additional sources were observed during the
same VLA and ATCA programs, and 3 of them have been published
(2001AJ....121.1241D 2001AJ....121.1241D).

Note (1): The filenames follow the ISO 9660 standard convention,
and were named NNNNNNNN.fit after the name of the USS source, as
listed in appendices A.1 to A.3, by dropping the prefix and sign of
the declination. This transformation is unique, and the translation
from filename to source name is listed below (sorted by sample in the
same order as the tables A.1 to A.3). The telescope with which the
radio map was obtained is also included.
