General Description

This is a long-slit spectroscopic observation of the Lyman-alpha emission
 that lies inside the damped Lyman-alpha absorption at z=2.43 in the spectrum of
 a faint (B=19) background quasar.
The emission comes from a galaxy that should be roughtly aligned with the quasar.
 
Spectrophotometric calibration is required to measure the flux in the emission.
Observing at 3 different slit angles will constrain the exact position of the galaxy
 by triangulation. Note that the quasar should be very well centered in the slit,
 especially in case of excellent seeing.
