An image database. II. Catalogue between δ=-30deg and δ=70deg.
A preliminary list of 68.040 galaxies was built from extraction of35.841 digitized images of the Palomar Sky Survey (Paper I). For eachgalaxy, the basic parameters are obtained: coordinates, diameter, axisratio, total magnitude, position angle. On this preliminary list, weapply severe selection rules to get a catalog of 28.000 galaxies, wellidentified and well documented. For each parameter, a comparison is madewith standard measurements. The accuracy of the raw photometricparameters is quite good despite of the simplicity of the method.Without any local correction, the standard error on the total magnitudeis about 0.5 magnitude up to a total magnitude of B_T_=17. Significantsecondary effects are detected concerning the magnitudes: distance toplate center effect and air-mass effect.

| KISO survey for ultraviolet-excess galaxies. XV
The fifteenth list and identification charts of the ultraviolet-excessgalaxies are presented. These galaxies were detected on the multicolorplates taken with the Kiso Schmidt telescope for 10 survey fields. Inthe sky area of 300 square degrees 544 objects are cataloged down to thephotographic magnitude of about 17.5.
