From the VSAT data it is also possible to study the coincidence of a single tag electron in VSAT and a high energy electron in the STIC detector. If the VSAT background is cut away efficiently enough, this will result in a new set of double tag data in the Q2 region of 20-100 GeV. As a result of this, the cuts on the maximum number of tracks and energies in the hadronic system must be removed, so that no important events are cut away.
To achieve good purity in the data sample, only STIC events with an angle greater than three degrees and an energy above 40 GeV were accepted. The normal cut-maps were applied to the VSAT data, resulting in a purity above 85%. In total 223 STIC+VSAT double tag events were found after the imposed cuts, with an expected background of about 33 events. This shall be compared with the 218 events seen in Monte Carlo, which is slightly higher but within the expected errors.
