Decreasing charge transfer efficiency in the STIS CCD has a detrimental effect on faint spectra acquired at the default location at the center of the chip. For signal levels of 50-100 e-, 10-15% of the charge can be lost during readout. For spectra of point sources and compact objects such as galactic nuclei, the full length of the slit is not needed. A target location closer to the read-out amplifier near the end of the slit can decrease the charge lost during parallel transfers by a factor of ~5. This proposal will determine precise locations for new pseudo-apertures to be defined centered at row 900 on the CCD, measure throughputs for those locations relative to the slit center, verify the spectral trace form at that location, and validate ACQ/PEAK procedures for acquiring targets in the narrow 52X0.05 and 52X0.10 apertures at those locations.
