Re:NGC 4775
NGC 4775 is an Sd galaxy, for which very little is known from previous studies.
The metal lines (Fe5015 and Mgb) seem to be centrally concentrated, while
H{beta} is low over an extended central area, and higher in the surrounding
region. The maps are not symmetric with respect to the centre. The galaxy is
young in the nucleus and has older ages in an annular (extended) region around
the centre; the metal content is everywhere low, and peaks in the centre.
Constant star formation cannot be ruled out, and is selected over a large part
of the field when allowing one to choose among constant and exponentially
declining star formation.

Re:NGC 4775
NGC 4775.---Sd: Small, elliptical bulge. Inner disk is irregular, with
no clear spiral pattern. Spiral pattern in the outer disk is very
faint and asymmetric. The dominant arm is very open, broad, and
diffuse. It originates on the SE side of the disk and curves to the
NW. It can be traced for ~180deg. The arm originating on the NW side
of the disk is higher surface brightness, but very short and stubby.
There are obvious knots in the arms/disk.

The arms of NGC 4775 are filled with
HII-region candidates, the largest of which are
complex and resolve into a combined halo diameter
at about the 4" level. The redshift of NGC 4775
is v_o = 1375 km/s.
A large number of candidates for dE, Sm,
and Im dwarf companions exist in the 2^deg^ field
surrounding NGC 4775.

S...: (RC1)
eccentric nuclear region

5. 1964RC1...C...0000d
Re:NGC 4775
Very small, bright nucleus. Several, partially resolved, filamentary,
branching arms. Asymmetric.

6. 1963MCG3..C...0000V
Re:MCG -01-33-043
Shocking example of densely curved arms [Si] with extremely strong
HII regions; it does not agree with the classification of Hubble
and others, and is similar to -01-33-034. Type: Sand - Sc, vB -
Sc* III, Morg - aS1. Redshift: +1555, emission from condensations.

7. 1956AJ.....61...97H
Re:NGC 4775
HMS Note No. 154
Slit on nucleus and emission patch.
Redshift is the average of measurements for both,
since the spiral is nearly normal to line of sight.
HMS Note No. 155
Emission patch 30 arcsec [south] of nucleus.
