“…THE CATALOGUE Preparation of the catalogue follows the methods described in two earlier papers (Mills and Slee 1957;Mills, Slee, and Hill 1958); subsequently these papers will be referred to as paper I and paper II respectively. The catalogue is divided into three zones covering declinations -20° to -30°, -30° to -40°, and -40° to -50°; they are given in Tables 1, 2, and 3.…”

“…A catalogue of radio sources has now been prepared between declinations -20 0 and -50 0 to add to the previously published catalogue between +10 0 and -20 0 (Mills, Slee, and Hill 1958); the zone between -50 0 and -80°, which will complete the series, is in preparation. In the present catalogue a total of 892 radio sources is listed in the area of 2·66 steradians.…”

SummaryA catalogue has been prepared of the radio sources observed between declinations _20 0 and _50 0 , using the Sydney cross-type radio telescope at a wavelength of 3·5 m ; a total of 892 sources is listed. This supplements an earlier catalogue in the declination zone + 10° to _20°. In addition to the positions and intensities of the sources, angular sizes of 50 of the strongest are given: several are found to have a size less than 15" arc. As before, identifications with bright optical objects have been sought, and a number of galaxies of apparently abnormal radio emission listed. Statistical analyses of the distribution of the radio sources give results very similar to those obtained using the earlier catalogue. \Vithin the uncertainty in the data, the distribution appears uniform in depth and there is a siguificantly greater number of sources of large apparent size than expected from chance blending effects.

“…A visibility amplitude based on only one observation is marked with a colon. The sources are identified either by familiar names of long standing, or by their numbers in the 3C, CTA, or CTB surveys or in the first survey of Mills, Slee and Hill (1958). "Coma A" is the source so designated in the Jodrell Bank survey of the region containing the Coma cluster of galaxies (Large, Mathewson, and Haslam 1959).…”

“…Several galactic sources of relatively small diameter were selected from Wilson and Bolton's survey of the galactic plane (1960), which we will call CTB. A few additional sources from the 3C catalog or from the first catalog of Mills, Slee, and Hill (1958) were added to fill gaps in the observing program.…”

The Caltech variable baseline interferometer has been used in a program of brightness distribution measurements on 19$ discrete radio sources at a wavelength of 31.3 em. This paper reports measurements, made with an east-west interferometer baseline, of the complex visibility functions of 127 sources. The amplitude and phase of the visibility functions were measured at transit with antenna spacings of 195~, 389~, 779~ and 1557~. Using these same basic spacings, and by observing at large hour angles, the visibility amplitude was measured at ten other effective spacings between 126~ and 1363~. Not all sources were observed at all spacings. The data are presented in tabular form, and graphs of the visibility amplitude as a function of antenna spacing are given for 51 of the more interesting sources. The interpretation of these data in terms of source brightness distributions will be given in another paper.

The primary purpose of this' communication is to report some modifications to two of the three radio source catalogues based on the Mills Cross pencil beam survey of sources at 85·5 Mc/s (Mills, Slee, and Hill 1958. These catalogues will subsequently be referred to as MSH.A considerable proportion of the modifications have resulted from a careful reexamination of our records between declinations +10° and -10°. This reappraisal was made with a view to obtaining a clearer picture of the discrepancies with the Cambridge 3C source survey (Edge et al. 1959) which overlaps ours in this band of declinations.A secondary purpose of this paper is therefore to make some general comments on the degree of confirmation of the revised MSH sources by the 3C survey in the overlap region.The modifications to MSH are given in Tables 1, 2, 3, and 4 below. They include the addition of sources to, and the deletion of sources from, the catalogues, alterations to data regarding other sources, and the clarification of a number of duplications which unfortunately eluded our scrutiny prior to publication.The method of reexamination of our records in the declination range +10° to -10° was as follows. We first examined our records in regions where there are 3C sources but no corresponding MSH sources, or where the correspondence was uncertain. There were 59 3C sources involved. In every instance our records were examined at the 3C position and around its northern and southern (declination) lobeshifts. MSH data involved were also checked. In addition a number of other MSH sources (37 in all, stronger than 20 x10-26 Wm-2 (C/S)-l at 85·5 Mc/s) were rechecked because the Kellermann and Harris (1960) interferometer observations at the California Institute of Technology Radio Observatory suggested that they were doubtful. A further 6 MSH sources listed by Bennett and Smith (1961) as being doubtful were also rechecked. § In all these instances modifications were made to our published data only if reinterpretation seemed necessary on the basis of our own records.
