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)

APPLICATIONS

• Study of the compact components and monitoring of possible variations (QSO structure, stellar mass function in the lens)

• Study (morphology and redshifts) of the extended emission (QSO host, models of the lens galaxy, high redshift galaxies)

• Study of the lens galaxy (absorption and extinction)
