Scientific Meeting of the Spanish-Astronomical-Society (SEA) (8th; 2008; Santander, Spain). This work has been supported by the Spanish Ministry of Education and Science through the research projects AYA2006-15698-C02-02, and AYA2006-2358, and by project ASTRID (S-0505/ESP/000361), funded by the ‘Comunidad de Madrid’ government.We present a short summary of the activities developed by GUAIX, the Universidad Complutense de Madrid (UCM) Group of Extragalactic Astrophysics and Astronomical Instrumentation. At present we are focused in the development of data reduction pipelines for several future instruments for the Spanish 10m GTC (Gran Telescopio Canarias). The careful treatment of the random error propagation throughout the data reduction is one of the main improvements of those pipelines. The first hardware development leaded by the GUAIX group will be FISIR, a fully-cryogenic (optimized for the K band) tunable filter in the near-infrared, to be installed within CIRCE, a near-IR camera for GTC.engjournal articlehttp://dx.doi.org/10.1007/978-3-642-11250-8_146https://link.springer.com/restricted access52AstronomyAstrophysicsAstrofísica
