5. Crowded Field Spectroscopy CASTLES

6. Crowded Field Spectroscopy B 1359 + 154

7. Long-Slit Mapping Several exposures are needed to scan the GL system (inefficient) Different bits of information are recorded under different atmospheric and instrumental conditions (differential atmospheric refraction)

17. Gravitational Lenses Task Goals Scientific aims Observational strategy Targets Instruments Tools (inputs from other tasks...) Team Scheduling

18. GLs Task - Goals Catalogue ? Good quality observations of a reduced group of selected objects Explore innovative techniques of analysis Diseminate IFS among GL researchers Profit from the net

19. GLs Task - Scientific aims Study of microlensing, specially during an High Magnification Event  study of the quasar unresolved structure Map the extended emission  model the galaxy mass distribution and study the quasar host galaxy Gravitational telescope  study high z galaxies

20. GLs Task - Observing strategy Spectral monitoring (microlensing) ToO ? (HME) Complementary observations of a well known system (extended emission in QSO 2237 + 0305)

21. GLs Task - Targets Multiple imaged QSOs  best candidates to microlesing, candidates to have extended emission Q 2237 + 0305 Giant Arcs

22. GLs Task - Instruments Performances Availability in the next (three) years Proposals Observations

23. GLs Task - Tools Data analysis tools (inputs from other tasks) Scientific tools (inverse mapping, GLs models, etc.)
