“…1210+121: Hazard & Murdoch (1977) proposed that this object was the optical counterpart of a radio source in the Molongo Catalogue (Sutton et al 1974); the separation was, however, 16 00 . Zotov & Tapia (1979) reported large optical variability and polarization, apparently reinforcing the identification.…”

We report on ESO Very Large Telescope optical spectroscopy of 42 BL Lacertae objects of unknown redshift. Nuclear emission lines were observed in 12 objects, while for another six we detected absorption features due to the host galaxy. The new high signal-to-noise ratio spectra therefore allow us to measure the redshift of 18 sources. Five of the observed objects were reclassified as either stars or quasars, and one is of uncertain nature. For the remaining 18 the optical spectra appear without intrinsic features in spite of our ability to measure rather faint (equivalent width $0.1 8) spectral lines. For the latter sources a lower limit to the redshift was set, exploiting the very fact that the absorption lines of the host galaxy are undetected in the observed spectra.

“…( 1) s, (Jy) The counts in the range 2-10 Jy for the MCI catalogue were subject to large statistical uncertainties due to the small number of sources, but the publication of the MC2 and MC3 catalogues (Sutton et al 1974) has extended the solid angle covered from 0·16 to 0·40 sr, with a consequent reduction in the uncertainties. Count corrections were not available for the MC2 and MC3 surveys, and hence their results were used only above 1· 77 Jy, where the corrections would be negligible.…”

“…Counts from both zones are given in the present paper. In addition, the publication of the MC2 and MC3 catalogues (Sutton et al 1974) allows improvement of the count statistics in the region 2-10 Jy, which was not well covered by MC1 alone.…”

Aust, J. Phys., 1977,30, 241-9 Number-flux density counts of radio sources are given for the first two deep surveys made with the Molonglo Mills Cross at 408 MHz, extending to lower limits of 84 and 88 mJy. Practical techniques are developed for the calculation of corrections to the counts when confusion errors are significant. The resulting corrections due to noise, confusion and other effects are given. Counts are also given for the MC2 and MC3 catalogues in the range 2-10 Jy to reduce the statistical uncertainties there. Results are shown on a composite plot, using relevant Molonglo surveys and an all-sky catalogue of strong sources. The existence of a convergence in the number of weak sources is confirmed.

Several catalogues of radio sources at 408 MHz have been prepared from observations made with the Molonglo cross telescope. These include (in chronological order) ‘The Molonglo Radio Source Catalogue 1’, the MC1, by Davies et al. (1973), the MC2 and MC3 by Sutton et al. (1974), MC4 by Clarke et al. (1976), ‘The Molonglo Deep Sky Survey of Radio Sources’ by Robertson (1977a,b,d) and ‘The Molonglo Reference Catalogue of Radio Sources’ (MRC) by Large et al. (1981). The catalogues MC1-4 cover selected areas of sky to a flux density limit of ~0.2 Jy to 0.3 Jy. The MRC includes extragalactic radio sources between δ = +18° and δ = −85° and is essentially complete at S408 = 1.00 Jy with raany sources to ˜0.7 Jy. The Wyllie (1969a,b) scale of flux density is used throughout.
