New upper limits for pulsed soft X-rays from the VELA pulsar PSR 0833-45 .
Abstract
In January 1977 the pulsar PSR 0833-45 was observed by a rocket experiment consisting of 12 X-ray paraboloidal collectors. No indication for pulsed flux could be detected. The new upper limits are considerably lower than former measurements in the energy band 0.09 to 2 keV.
