Final results are presented for a March 20, 1963 search for night sky sources of soft X-rays. Although one sky region was found to be associated with an X-ray flux 2,5 to 3 standard deviations above background, the probability of observing one random fluctuation of this importance in the data for the night sky is estimated to be as high as 20%. The region is located at α= 23 h 40 m, δ = + 78°. Apparently negative results from a search of the data for variations of X-ray background with galactic latitude are presented and discussed.

On donne, les résultats finaux de la recherche de sources de rayons X mous dans le ciel nocturne (20 mars 1963). Une seule région du Ciel a fourni un signal supérieur à 2,5 à 3 fois l'écart statistique le plus probable alors que la probabilité d'observer un écart statistique fortuit de cet ordre est de 0,2. La région est située à α = 23 h 40 m, δ = + 78°. Il ne semble pas у avoir de variations du fond galactique émettant des rayons X mous avec la latitude galactique et ce résultat est discuté.

Резюме

Резюме

Даны окончательные результаты расследования источников мягких лучей X в ночном небе (20 марта 1963). Только один участок неба дал сигнал превышающий в 2,5-3 раза наиболее вероятное статистическое отклонение, тогда как вероятность наблюдать случайное статистическое отклонение этого порядка равна 0,2. Участок определен координатами α 23 =3D 40 м 8 =3D + 78°. Как будто нет изменений галактического фона, излучающего мягкие лучи X, с галактической широтой и этот результат обсужден.
