Paper Abstract

NEFER (Nuevo Espectrómetro Fabry-Perot de Extrema Resolución) is a high spectral resolution, scanning Fabry-Perot Spectrometer. It will be installed in the OSIRIS instrument at the GTC 10 m telescope. This 3D instrument uses a high order scanning Fabry-Perot to obtain highly accurate kinematical information of extended cosmic sources such as galaxies or nebulae. Astronomical data obtained with this instrument lead to a 3D spectroscopic data cubes composed of several images, each one at different gaps of the scanning Fabry-Perot Interferometer. In this work we present laboratory testing of some characteristics of the ICOS Fabry-Perot acquired for this instrument such Finesse, free spectral range, and peak transmission. We also present software design and development for the 3D data reduction standalone package of this high resolution 3D instrument.
