Optical identification and spectroscopy of X-ray sources precisely positioned with A-3Using a scanning modulation collimator, the optical identification of X-ray sources by means of precise positioning was carried out. Two galactic identifications (4U2129+47 and 2A0311-227) and two extragalactic identifications (NGC 526a and Parkes H2155-304) are described.
