New Galaxies with UV Excess. VI
A list is presented of 122 new galaxies with UV excess observed onplates obtained using the 40″ Schmidt telescope at the ByurakanObservatory with a 1°.5 objective prism. It is shown that therelative number of galaxies with a strong UV excess (classes 1 and 2)listed in Table 1 is roughly 55.7%. This is 6.7% higher than for thepreviously observed galaxies. These samples also differ in terms of themorphology of the spectra. The largest deviation, approximately 9.9%,occurs for type “sd.”
| 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.
