S. Arribas et al., Differential atmospheric refraction in integral-field spectroscopy: Effects and correction - Atmospheric refraction in IFS, ASTR AST SS, 136(1), 1999, pp. 189-192
The basic concepts for determining the effect of differential atmospheric r
efraction on integral-field (two-dimensional) spectroscopic observations ar
e presented, and a method for correcting the spectra from this effect is gi
ven. The method is demonstrated with real data.
