The CfA Redshift Survey: Data for the South Galactic Cap*
TL;DR: In this paper, the authors present redshifts for a sample of 4391 galaxies with magnitude mB(0) ≤ 15.5 covering 20h ≤ α ≤ 4h in right ascension and -25 ≤ δ ≤ 90° in declination.

Colour-differential interferometry for the observation of extrasolar planets
TL;DR: In this paper, the authors present the high angular resolution technique of colour-differential interferometry for direct detection of extrasolar giant planets (EGPs) in the near-infrared.
Journal ArticleDOI
Optical detectors for spectroscopy
TL;DR: The modes of operation of photoconductive and photoemissive array detectors are described, and their performance characteristics compared and contrasted, with emphasis on their suitability for use as detectors for optical spectroscopy as discussed by the authors.
