• Multi-conjugate adaptive optics VLT imaging of the distant old open cluster FSR 1415 

      Momany, Yazan; Ortolani, Sergio; Bonatto, Charles Jose; Bica, Eduardo Luiz Damiani; Barbuy, Beatriz (2008) [Artigo de periódico]
      We employ the recently installed near-infrared Multi-Conjugate Adaptive Optics demonstrator (MAD) to determine the basic properties of a newly identified, old and distant, Galactic open cluster (FSR 1415). The MAD facility ...
    • Wavelength self-calibration and sky subtraction for Fabry-Pérot interferometers : applications to OSIRIS 

      Weinzirl, Timothy; Aragón-Salamanca, Alfonso; Bamford, Steven Peter; Rodríguez del Pino, Bruno; Gray, Meghan E.; Chies-Santos, Ana Leonor (2015) [Artigo de periódico]
      We describe techniques concerning wavelength calibration and sky subtraction to maximize the scientific utility of data from tunable filter instruments. While we specifically address data from the Optical System for Imaging ...
