... We present the first results of the ESO/GOODS program of spectroscopy of faint galaxies in the Chandra Deep Field South (CDF­S). 399 spectra of 303 unique targets have been obtained in service mode with the FORS2 spectrograph at the ESO/VLT, providing 234 redshift determinations (the median of the redshift distribution is at 1.04). ...

... A GRIM Spectroscopy Primer . ... SLIT WIDTH . ... It may take more than one iteration of the procedure for calculating the offset before you land your object(s) on the slit, but taking a short-duration exposure in "Spectral" mode once you think you're there will help confirm the pointing. ... The image header variables FILTER1, FILTER2, LENS, GRISM, SLIT give the current status of GRIM II's mechanical configuration. ... This document summarizes both types of GRIM keywords and provides usage examples...
