to note |
||||||||||||
| – | Morphology
matters, also field vs. cluster. |
||||||||||||
| – | L*
or M* in rich clusters isn’t a bad “standard candle” |
||||||||||||
| – | cD
galaxies in cluster centers are special cases; they are |
||||||||||||
| like
massive ellipticals but have extra stellar envelopes. |
|||||||||||||
| They
do not fit extrapolations of ellipitical LFs. |
|||||||||||||
| – | Low
luminosity end of LFs not well determined (Irr and |
||||||||||||
| dwarf
ellipticals). Again SDSS will
probably be the best |
|||||||||||||
| word
on this (if it goes faint enough). |
