Positions and evidence for a steady component for X-ray burst sources


DURING observations of the galactic centre region with the Ariel V RMC experiment we have observed X-ray flux from two sources within the error boxes for the burst sources MXB 1730–335 and MXB 1728–34. The observations were made in RMC mode and represent integrations over periods of about one satellite orbit (100 min). This is distinct from the time mode used for the observations described in a companian paper (to be published) in which the time resolution is 32s but with which no spatial resolution is possible.
