First results of X-ray pulsar observations with the ART-P telescope onboard “GRANAT” observatory

Coded mask telescope ART-P onboard international astrophysical observatory “GRANAT” is capable to reconstruct images of 1.8 × 1.8 (FWHM) fields of sky and to obtain spectra of sources in 4–30 keV energy range. Telescope is operation in “photon by photon” mode with time resolution ∼4 ms, which makes this telescope appropriate for X-ray pulsar observations. First results of some well known pulsar observations in 1990 February–August are presented below.
