NGC 5574 would be classified as a pure S0
on low-resolution plates. The listed type is S0_1_(8)
in the RSA1 and is SB0? in the RC2, both based
on a 1925 Mount Wilson 100-inch plate by
Hubble. The Las Campanas du Pont 100-inch
plate by Babcock here shows the same feature of
massive stubby arms as in NGC 4143, above.
The arms are not visible in this reproduction but
are well seen on the original plate. The deviation
from symmetry, where the bulge merges with the
disk, is less pronounced than in NGC 4143,
classed as S0/Sa. This smaller deviation of the
morphology from pure S0 form is noted by the
classification of NGC 4143 as S0/a, rather than
S0/Sa.
NGC 5574 forms a pair with NGC 5576
[E4(tides?)], which is 163" northeast of NGC
5574. The redshifts are similar at v_o(5574) =
1612 km/s and v_o(5576) = 1424 km/s. From
the mean redshift distance of 30 Mpc (H = 50)
the projected linear separation is small, at 24
kpc. NGC 5576 is shown in the E section on
panel 9.

NGC 5574: This small S0, "satellite" of NGC 5576, is surrounded with
an envelope of marked spiral structure.
