Abstract
This is one of extractions from Gabutzda related BL-Lac polarization observations. The source was allocated to FQID=2, so specifing this parameter is reqired for CLCAL and SPLIT. Due to UV coverage the higher resplution of space-GRT baselines was obtained only E-W direction. And the source was resolved into two component in E-W direction.
