The radio galaxies in our sample exhibit several properties that
have been noted before for other samples. To name a few:
- FR I galaxies are optically brighter but less luminous
in radio as compared to FR II galaxies.
- FR II galaxies show peculiarities more often than do the FR Is.
- Dust is more common in FR I galaxies.
These galaxies are also boxy in nature.
- FR II are more likely to contain a disk component.
They have pointed isophotes.
In the next chapter we show how ages for star bursts can be obtained.
