Scientific paper

This proposal has been revised 4/93 to compensate for current operational constraints. Observations of the lensed, 'clover leaf', Broad Absorption Line (BAL) QSO 1413+11 are proposed in order to achieve the following goals: (1) A PC image of the lensed QSO wil be taken at the time of the FOS observations so that relative photometry of the four QSO images can be performed. The results of this photometry will allow contamination from overlapping PSFs to be removed from the four FOS spectra. (2) FOS observations of the four QSO images will be used to check for sight-line dependent differences in the BAL profiles. The results can be used to place constraints on small-scale BAL cloud sizes and shapes. (3) The same FOS observations will be used to check for sight-line dependent differences in intervening, narrow metal absorption line systems. The results can be used to place constraints on narrow line system cloud sizes and shapes.
