Bivariate Brightness Distribution
Correct observed SB-magnitude distribution for incompleteness and volume sampled (as functions of M and ?) ? intrinsic ?(M,?).
Main features:
- Giants have bounded ~Gaussian 2D distn.
- Dwarfs are steeply increasing at faint L.
- Giant LSB galaxies rare.
- Sharp HSB cutoff at all luminosities.
- BBD falls off before low-SB selection limit.
- Isophotal corrections?
