Simple spectroscopic program of 4 objects in the same field, aimed to
prove that this is a gravitationally lensed system.
The two OBs are such that each of them will place the long slit
across two of the targets at the same time, so that only two 
science exposures are required to get all four targets.

This program is very short. The total exposure time is 07min and 20sec.
It was ranked A by the OPC. It must be executed during dark time, with 
seeing better than 0".6. The users emphasize the fact that the slit has
to be accurately positioned.
