Observers: Stefan Taubenberger, Stephan Hachinger

Data reduction team: Nancy Elias-Rosa, Antonia Morales-Garoffolo

3nd/last night of 2nd subrun (only EFOSC2).

All observations turned out to be good quality. Airmass values are quite approximate because of changes w/r/t the original schedule.

All acqusitions for spectra (except for stdstars) with NarrowSlit template, slit stable at y=992.
