General Description

This program is aimed at obtaining the stellar metallicities of a sample
 of galaxies at z~3 by measuring metal absorption features in their UV-rest frame
 spectrum. Several of these sources are weak, and the continuum may not be detected
 in invidual exposures. All OBs are IDENTICAL, by simply repeating the same MXU observation
 with the same mask. Only the starting position of the targets along the slits differs
 a little (~1 arcsec) in each OB.  The location of the reference stars is indicated
 with a cyan circle (finding chart directly obtained with FIMS).

Waiver Requests

We requested a waiver to change the grism to GRIS-300I+21,OG590+32 with
 respect to the originally proposed one (GRIS-300V+20,GG435++81). This waiver was
 requested on July 22 and approved on July 28 (082.A-0398A.01.WAV)
