New results on the mid-IR emission of Seyfert galaxies are presented. The observations were performed using the TIMMI-2 instrument at the 3.6 m ESO telescope. We have obtained diffraction-limited images. In some cases the emission can be resolved and varies with wavelength. The relevance for these studies for CANARICAM is briefly discussed.

The techniques and software tools developed for the reduction and analysis of ISO-CAM/PHOT data with the LARI method are presented together with some highlights from the results obtained thanks to their application to different fields. Designed for the detection of faint sources in ISO raster observations, such method is based on the assumption of

The planning of the ISOPHOT (Lemke et al. 1996) calibration during the Performance Verification (PV) phase, with its 4 day turn-around cycle, required mission planning tools in the hands of the Instrument Dedicated Team (IDT). We developed a system, that gave full command of all instrument functions and which allowed planning of the observations

Interaction can be the main mechanism that triggers star formation in Wolf-Rayet galaxies. The compact group HCG 31 has one of this objects, NGC 1741. We present new observations of this compact interacting group, in order to analyse the physical conditions and chemical composition of the ionized gas, as well as to estimate the ages of the

ELMER is a visible imager spectrograph currently scheduled to be in operation at the GTC on Day One. This paper covers engineering aspects of the instrument and summarizes five poster contributions presented at this conference. ELMER is an instrument managed directly by the GTC Project Office, which has developed the preliminary design and large

Taking into account effects of hyperfine structure, we calculated the synthetic solar spectrum for wavelength intervals around nine neutral manganese lines. To estimate values of hyperfine components we used the Oxford total absorption oscillator strength measurements (Booth et al. 1983). We compared observed profiles (Photometric Atlas of the
