- Phillips et.al. (1987) studied a 4.5
x 4.5 area
in the Fornax cluster from the Southern Sky survey (using APM). They found 1550 galaxies, and two
`galaxy populations':
- "Normal" galaxies; (0) = 21.75, 20.7
(0)
24.2
- "LSB" galaxies; (0)
22.5, with
a flat distribution in the range 22.5
(0) 24.2
, and that although a low surface brightness
population does exist, it
is not very numerous.
- "Normal" galaxies;
- 1993 Bosma and Freeman published a paper concluding that of all the spiral galaxies in the
SRC-J survey, 80% follow the (0)=21.65 B
law.
