We present a new technique for performing two-dimensional (integral-field) spectroscopy of objects with a large range in intensity. It is based on the capability of optical fibers to discretize the intensity distribution at the telescope focal plane. This allows not only reformatting but also the equalization of fiber output intensities, matching

We present accurate measurements of the central wavelengths of 4947 atomic absorption lines in the solar optical spectrum. The wavelengths, precise to a level ~ 50-150 m s(-1) , are given for both flux and disc-centre spectra, as measured in relatively recent FTS solar atlases. This catalogue modernizes existing sources based on photographic

We present two-dimensional spectroscopy of the gravitational lens system Q2237+0305 (Einstein Cross) obtained with the INTEGRAL fiber system in subarcsecond seeing conditions. The four components of the system appear clearly separated in the continuum intensity maps. However, the intensity map of the C III] lambda 1909 line exhibits an arc of

Observations are presented of high resolution interstellar Na I D and K I (lambda 7699 Angstroms) line profiles towards 7 stars in the globular cluster NGC 6541 and 3 field stars within 3° of the cluster. It is seen that the gas in this general direction (l, b ~ 350°, -11°) shows a complex structure, having the greatest number of components yet
