Abstract

All of the observations were made using the Hubble Space Telescope Faint Object Spectrograph. Every QSO chosen for our program was observed using the G190H grating, with a resolution of R{~=}1300, and a wavelength coverage from about 1600{AA} to just above 2310{AA}. When there was a sufficient difference between the estimated exposure time needed for the G190H observations of a QSO, and the time used in the total number of orbits needed to complete the observations, the G270H grating setup was also used in the remaining time. Because the G130H grating was never used, all observations were taken using the FOS Red detector. The observations made for this program were taken in ACCUM mode, in which the accumulated detector counts are read out and recorded in intervals of about 2 minutes during each orbit. Two of the archival spectra (B201 1257+34 and TON 153), were taken in RAPID mode, in which the detector is read out in much shorter intervals.
