摘要：

We present IR observations of a homogeneous sample of Seyfert 1 galaxies that we also observed with CCDs in optical bands. We have K-band frames for 41 objects, and JHKL photometry for 27 of these with the UK Infrared Telescope. Methods of separating the galaxian and nuclear fluxes are presented and discussed. The nuclear and galaxian K magnitudes are derived with their errors. Our data support the claim that Seyfert galaxies usually are early-type spiral or SO galaxies.
