A revised set of flux density estimates is presented for the radio source
1934-638, over the frequency range 1.4GHz to 8.6GHz. The main purpose
of this revision is to bring the ATCA flux density scale into better
agreement with the scales used at Northern hemisphere observatories, the
VLA in particular. The revised scale defined here is believed to be
consistent with current Northern scales at the 1
2% level over the
range 1-10GHz. It is recommended that the revised scale be
implemented as the default option in all ATCA observing and reduction
software, as it represents a significant correction to the scale currently
in use.
