Objective and Consistent Stellar Magnitudes from the Palomar Sky Survey Prints

Print copies of the Palomar Sky Survey (PSS) are widely used for optical identifications of radio sources north of δ = -33°.

Optical Spectra of Southern Molonglo Radio Sources — II

This is the second of a series of papers presenting detailed optical spectra for QSOs and strong-emission-line galaxies identified with radio sources from a selected area (−15° to −23° in declination) of the Molonglo Reference Catalogue (MRC: Large et al . 1981). The catalogue is complete to 1 Jy at 408 MHz although it contains many weaker sources. First results were reported by Hunstead et al . (1978, Paper I) and a summary was given by Hunstead (1979). Results have also been given by White et al . (1980) for spectra of QSOs identified with radio sources to a much deeper level of 88 mJy from a small strip within the larger selected area.

A Confusion Limited Radio Survey from the Molonglo Cross

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 S 408 = 1.00 Jy with raany sources to ˜0.7 Jy. The Wyllie (1969a,b) scale of flux density is used throughout.

The Sensitivity of the V/V m Test to Uncertainties in Observed Parameters

Schmidt (1968) and Rowan-Robinson (1968) developed a simple and concise test for the uniformity of the distribution of quasars (QSOs) based on QSO luminosity and occupied volume.
