The catalogued ATHDFS radio sources were crossmatched against the positions of optical sources in the CTIO catalogue. The CTIO imaging covers a region 44 x 44 arcmin in extent.

All but 11 sources lie within the CTIO imaging, and these are :
ATHDFS_J223304-605752
ATHDFS_J223326-605729
ATHDFS_J223256-605656
ATHDFS_J223246-605654
ATHDFS_J223403-605640
ATHDFS_J223244-605609A
ATHDFS_J223244-605609B
ATHDFS_J223411-605545A
ATHDFS_J223411-605545B
ATHDFS_J223309-605544
ATHDFS_J223315-605543

A description of the CTIO Counterpart Table is as follows:

Column (1) --- ATHDFS source name.

Column (2) --- CTIO flag. ``YES'' indicates there is a CTIO counterpart within the 1.8 arcsec matching radius. ``NO'' means there is no CTIO counterpart within the 1.8 arcsec matching radius. ``S'' indicates there is a nearby bright star which may affect the photometry.

Column (3) --- CTIO source ID, corresponding to the source number from CTIO catalogue (Palunas et al. APJS, submitted).

Column (4) --- U magnitude.

Column (5) --- rms error in U magnitude.

Column (6) --- B magnitude.

Column (7) --- rms error in B magnitude.

Column (8) --- V magnitude.

Column (9) --- rms error in V magnitude.

Column (10) --- R magnitude.

Column (11) --- rms error in R magnitude.

Column (12) --- I magnitude.

Column (13) --- rms error in I magnitude.

Column (14) --- CTIO photometric redshift.

Column (15) --- CTIO photometric redshift uncertainty.
