Description
The goal of this paper is to present the Transmission Matrix of the SPI Mask STM/QM Model. The experimental set-up used to determine INTEGRAL Spectrometer (SPI) Mask Transmission Matrix is hereafter described: collimation system, radioactive sources, energy ranges covered and pitch angles covering the expected SPI Field of View. The QM results fulfil transparency/opacity requirements. Same materials and manufacturing procedures have been used in both STM/QM and FM Masks, consequently we do not expect significant changes on the FM Transmission Matrix. Preliminary results of the Flight Model support this statement.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    MAAT: an IFU for GTC optimized using spectrograph wavefront measurements and superoptimization
    The Mirror-slicer Array for Astronomical Transients (MAAT) is an IFU now being manufactured for the OSIRIS spectrograph on the 10.4-m GRANTECAN (GTC) telescope at La Palma. It is based on the Advanced Image Slicer (AIS) concept as are MUSE and KMOS on the VLT (among many others). Very significant changes to the design had to be made due in part to
