A comparison is made between the ultraviolet stellar fluxes measured by three sets of observers. The comparison is extended to visible and near ultraviolet measurements. Absolute intensities are compared in all cases and an enhanced ultraviolet emission is noted in i Ori. The well known ultraviolet deficiency is found in other cases.

On compare, les valeurs de flux stellaires ultraviolets obtenus par trois groupes d'observateurs. Cette comparaison est étendue au domaine visible et ultraviolet proche. Dans tous les cas on porte attention aux intensités absolues : on note un excès d'ultraviolet dans ι Ori, un défaut Xultraviolet dans tous les autres cas.

Резюме

Резюме

Сравнены значения ультрафиолетовых звездных потоков полученных тремя группами наблюдателей. Это сравнение распространено на видимую область и на ближайшую внимание на абсолютные интенсивности; отмечается избыток ультрафиолетового излучения в ι Ori, недостаток ультрафиолетового излучения во всех других случаях.
