Frequencies and splittings of low-degree solar p modes: Results of the Luminosity Oscillations Imager
Published online by Cambridge University Press: 30 March 2016
Extract
The design of the LOI instrument was an original idea of Andersen et al. (1988). It consists of a Ritchey-Chrétien telescope (f=1300 mm) imaging the Sun through an 5-nm passband interference filter at 500 nm. The image is projected on a photodiode array detector built to our specifications (Appourchaux et al., 1992). The detector is made out of 12 scientific pixels and of 4 guiding pixels. The shape of the scientific pixels are trimmed to detect low degree modes for l < 7 (Appourchaux and Andersen, 1990). The guiding pixels are 4 quadrants of an annulus with an inner and outer radius of 0.95 and 1.05 solar radius, respectively.
