Abstract:
Photometric scaling relations are studied for S0 galaxies and compared
with those obtained for spirals. New two-dimensional multi-component
decompositions are presented for 122 early-type disc galaxies, using
deep Ks-band images. Combining them with our previous decompositions,
the final sample consists of 175 galaxies (Near-Infrared Survey of
S0s, NIRS0S: 117 S0s + 22 S0/a and 36 Sa galaxies). As a comparison
sample we use the Ohio State University Bright Spiral Galaxy Survey
(OSUBSGS) of nearly 200 spirals, for which similar multi-component
decompositions have previously been made by us.
