Simple program to obtain high-quality spectra of four relatively bright QSOs for an abundance study of four DLA systems towards these quasars. Change of one target approved by VISAS (as reported in README file). No special scheduling required. There are three to five OBs for each object, generally with the same setting. All OBs have an attached wavelength calibration (to be taken in the BLUE only), and are of 3600s or 4500s long (waiver 67.A-0022A.WAV approved). One bright, fast rotator hot star (V=6) needs to observed in the red setting R860 only, but at 2 different airmasses (1.2 and 1.6), to record the telluric lines. The P.I. has provided 2 possible targets at different R.A. for making the scheduling simpler. Only ONE needs to be observed.
