Transactions of the International Astronomical Union, 1985 X-ray astronomy has continued to flourish in the three years covered by the present report (to June 1987) despite the continuing scarcity of new missions. The European EXOSAT has probably made the greatest impact during this period, carrying out over 2000 separate observations up to it’s loss of attitude control in April 1986.

New distance measures for classifying X-ray astronomy data into stellar classes [PDF]
, 2018 The classification of the X-ray sources into classes (such as extragalactic sources, background stars, ...) is an essential task in astronomy. Typically, one of the classes corresponds to extragalactic radiation, whose photon emission behaviour is well ...
