UBR charge-coupled device photometry of Stromlo-APM galaxies
We present charge-coupled device (CCD) photometry in theJohnson-Kron-Cousins UBR bands for a sample of 320 galaxies selectedfrom the Stromlo-APM Redshift Survey. We use these CCD data to estimatethe galaxy luminosity function in the U, B, R and bJ bands,finding consistent results with earlier work. Fainter galaxiesserendipitously observed on our CCD frames allow a check of thephotometric calibration of the APM Galaxy Survey. We find no evidence ofany significant scale error in the APM magnitudes.

The K-band luminosity function of nearby field galaxies
We present a measurement of the K-band luminosity function (LF) of fieldgalaxies obtained from near-infrared imaging of a sample of 345 galaxiesselected from the Stromlo-APM Redshift Survey. The LF is reasonably wellfitted over the 10-mag range -26<=MK<=-16 by aSchechter function with parameters α=-1.16+/-0.19,M*=-23.58+/-0.42 and φ*=0.012+/-0.008Mpc-3, assuming aHubble constant of H0=100kms-1Mpc-1. Wehave also estimated the LF for two subsets of galaxies subdivided by theequivalent width of the Hα emission line atEW(Hα)=10Å. There is no significant difference in LF shapebetween the two samples, although there is a hint (~1σsignificance) that emission-line galaxies (ELGs) have M* roughly 1magfainter than non-ELGs. Contrary to the optical LF, there is nodifference in faint-end slope α between the two samples.

The Stromlo-APM Redshift Survey. IV. The Redshift Catalog
The Stromlo-APM Redshift Survey consists of 1797 galaxies with b_J_ <17.15 selected randomly at a rate of 1 in 20 from automated platemeasurement (APM) scans. The survey covers a solid angle of 1.3 sr (4300deg^2^) in the south Galactic cap. Redshifts have been measured for 1790(99.6%) of the galaxies. The median galaxy recession velocity is 15,300km s^-1^, and so the volume probed is V ~ 1.38 x 10^6^ h^-3^ Mpc^3^. Inthis paper we describe the construction of the redshift catalog andpresent the survey data.

The Catalog of Southern Ringed Galaxies
The Catalog of Southern Ringed Galaxies (CSRG) is a comprehensivecompilation of diameters, axis ratios, relative bar position angles, andmorphologies of inner and outer rings, pseudorings, and lenses in 3692galaxies south of declination -17 deg. The purpose of the catalog is toevaluate the idea that these ring phenomena are related to orbitalresonances with a bar or oval in galaxy potentials. The catalog is basedon visual inspection of most of the 606 fields of the Science ResearchCouncil (SRC) IIIa-J southern sky survey, with the ESO-B, ESO-R, andPalomar Sky surveys used as auxiliaries when needed for overexposed coreregions. The catalog is most complete for SRC fields 1-303 (mostly southof declination -42 deg). In addition to ringed galaxies, a list of 859mostly nonringed galaxies intended for comparison with other catalogs isprovided. Other findings from the CSRG that are not based on statisticsare the identification of intrinsic bar/ring misalignment; bars whichunderfill inner rings; dimpling of R'1pseudorings; pointy, rectangular, or hexagonal inner or outer ringshapes; a peculiar polar-ring-related system; and other extreme examplesof spiral structure and ring morphology.
