Write a brief summary of the data reduction and its outcomes} : Typical survey dataset with two GRTs (Shanghai+Kalyazin). Calibration was restarted from scratch because the amplitudes were very low due to the FITLD bug present in the 31DEC00 and 31DEC01 versions of AIPS. Kalyazin amplitudes have been scaled up by 3.5 based on previous data reduction experience and comparison with other baselines. In spite of the number of GRTs the uv-coverage was quite good. The image shows an extension to the South that may be real (though suspicious). Contact person for this experiment is Zsolt Paragi (paragi@jive.nl). #--------------------------------------------------------------------------- # Section 2 : Pre-AIPS Checklist #--------------------------------------------------------------------------- {PI letter retrieved (yes/no)} : y {Data quality reports and plots retrieved?
