Properties of nearby clusters of galaxies. IV. A147, A260, A272, A278, A1661, A2056, A2073, A2093, A2096, A2124
We present F band photometry from digitized plates obtained with 48-inchPalomar Schmidt for 1074 galaxies brighter than m_3+3 in 10 clusters.For each galaxy equatorial coordinates, magnitude, size, ellipticity andorientation are given. We provide the galaxy surface density maps foreach cluster. Tables 2 to 11 are only available in electronic form atthe CDS via anonymous ftp to cdsarc.u-strasbg.fr ( or viahttp://cdsweb.u-strasbg.fr/Abstract.html Figures 2 to 10 are onlyavailable in electronic form at http://www.edpsciences.org

Galaxy coordinates. II. Accurate equatorial coordinates for 17298 galaxies
Using images of the Digitized Sky Survey we measured coodinates for17298 galaxies having poorly defined coordinates. As a control, wemeasured with the same method 1522 galaxies having accurate coordinates.The comparison with our own measurements shows that the accuracy of themethod is about 6 arcsec on each axis (RA and DEC).

Linear clusters of galaxies - A194
New measurements for 160 redshifts and previous measurements for 108other redshifts are presented for galaxies within 5 deg of A194. Thegalaxy distribution in A194 is shown to be inconsistent with aspherically symmetric King model. A mass-to-light ratio is derived usingthe virial theorem which is lower than the mean for the groups in theCfA redshift survey (Huchra and Geller, 1982; Geller, 1984). Anonparametric test for galaxy-cluster alignment and a Chi-squared testare used to search for alignment of galaxy major axes with the axis ofA194. Evidence for neither luminosity segregation nor significantdifferences in the velocity or surface distributions of galaxies as afunction of morphological type is found.
