A further study of the relation of the radio-far-infrared in galaxies. I. Observations and data processing.

The radio luminosities of 99 galaxies at 6.3 cm (and of 31 of them at 2.8 cm) are determined on the basis of observations obtained with the 100-m Effelsberg radio telescope during March-August 1984 and compared to the IRAS color-corrected FIR luminosities, extending the survey of de Jong et al. (1985). The data-reduction procedures are described, and the results are presented in extensive tables and maps and briefly characterized. The correlation of radio to FIR luminosity is confirmed over about four decades in both parameters, and the dispersion of log P(6.3 cm)/L(FIR) is found to be about 0.2, which is significantly smaller than the dispersion found by de Jong et al. The improvement is attributed to color correction, integration over the 100-60-micron range, and the exclusion of ambiguous identifications.
