Notes. The first and second columns show the instrument and wavelength of each band, next to the angular resolution in the third column. The fourth column is the σrms of each band, expressed in units of Jy/beam, except for CO, which is in K km/s and for HI which is in Jy/beam m/s. The maps listed cover the whole disk of our two galaxies. Resolutions are FWHM on each map. HI data was only available for NGC 2976. The integrated flux at 2.8 cm and its corresponding uncertainty is quoted from Niklas et al. (1995) and was not measured for this work.
