These data are used to study the origin of the dwarf elliptical galaxy population inhabiting clusters. Description: The observing time that we obtained for this work was part of the International Time Program (ITP 2005-2007) at El Roque de los Muchachos Observatory. Here we focus on the medium resolution (R∼3800), long-slit spectroscopy carried out during three observing runs. In runs 1 and 3 (December 2005, February 2007) we used the ISIS double-arm spectrograph at the 4.2m WHT, and in run 2 (January 2007) we used the IDS spectrograph at the INT (2.5m telescope).
