Abstract:
We present 292 new redshifts of elliptical galaxies selected from the
APM Bright Galaxy Survey. We use these data together with published
redshifts and bj apparent magnitudes from the APM Bright Galaxy Survey
in order to estimate the shape of the Luminosity Function of a total
sample of 535 ellipticals. We use the Maximum Likelihood method for
the determination of the best fitting parameters α and M* of a
Schechter Function. In order to provide tests for systematics and
suitable error estimates we apply Monte Carlo techniques which are
also used to deal with incompleteness effects in the data. In
agreement with other authors our results indicate a relative lack of
low luminosity ellipticals compared to other morphological types. The
best fitting shape parameters derived are α=0.20±0.25 and
M*Bj=-20.0±0.3. We do not find evidence for a dependence of
these parameters on environment.
