PICARD SODISM, a space telescope to study the Sun from the middle ultraviolet to the near infrared
Autor: Meftah, M., Hochedez, J. -F., Irbah, A., Hauchecorne, A., Boumier, P., Corbard, T., Turck-Chièze, S., Assus, P., Bertran, E., Bourget, P., Buisson, F., Chaigneau, M., Damé, L., Djafer, D., Dufour, C., Etcheto, P., Ferrero, P., Hersé, M., Marcovici, J. -P., Meissonnier, M., Morand, F., Poiet, G., Prado, J. -Y., Renaud, C., Rouanet, N., Rouzé, M., Salabert, D., Vieau, A. -J.
The Solar Diameter Imager and Surface Mapper (SODISM) on board the PICARD space mission provides wide-field images of the photosphere and chromosphere of the Sun in five narrow pass bands (centered at 215.0, 393.37, 535.7, 607.1, and 782.2 nm). PICAR
