These biases are extremely severe beyond . such that a meaningful interpretation of generic galaxy evolution is not possible. We can however extract well defined volume-limited samples at . < 1. The data are entirely consistent with passive/null-evolution for elli

This is also the aim of the FORS Deep Field (FDF), which has about 5 times the field-size of the two Hubble Deep Fields together and, in addition, contains a relatively bright quasar of 18.5mag at . = 3.36 at its center. A full exploration of the FDF multicolor data requ

Hans Jürgen Ohlbach,Norbert EisingerI give examples of stellar work that is done with data collected in the course of extragalactic surveys, including the Hamburg/ESO objective-prism survey. I list some considerations to be taken into account for future (stellar) surveys.
