Abstract
The southern CfA2 galaxy data are used to investigate the scaling
properties of the galaxy number distribution. We construct two
volume-limited samples with galaxy magnitudes
![[FORMULA]](img1.gif)
and ![[FORMULA]](img2.gif)
,
and calculate the second- to ninth-order moments with the box-counting
method. On scales from 5 to 27 ![[FORMULA]](img3.gif)
M pc,
the moments exhibit multifractal scalings. From the exponents of the
scalings, we suggest that the galaxies lie in planar structures which
have filamentary dense regions.
