Write a brief summary of the data reduction and its outcomes} : This survey dataset is an extraction of the GOT experiment v019b. The extraction was received on tape from Socorro containing data for four GRTs plus HALCA. All but 3 GRTs at any one time were flagged before imaging in Difmap. LA,NL,SC are used during the first hour of data, and LA,MK,SC during the remaining three hours. Suggested parameters for all AIPS tasks were used. CALIB was not run so the final SN and CL tables have non-zero phases in them. Imaging and model-fitting both went very well and produced good results. Structure is seen in the survey image out to ~20 mas from the core, in good agreement with the USNO map at 8 GHz from 1997 Dec. #--------------------------------------------------------------------------- # Section 2 : Pre-AIPS Checklist #--------------------------------------------------------------------------- {PI letter retrieved (yes/no)} :y {Data quality reports and plots retrieved?

Include the global amplitude offsets that were applied if gscal was used} : Cleaned and phase selfcaled using uniform weighting, then switched to uvweight 0,-1 and a larger mapsize and continued cleaning and selfcaling to clean the extended structure. Global amplitude selfcal was applied, followed by a few more iterations of clean and selfcal. The global amplitude offsets were all within 10\%. The final image is displayed with uniform weighting. Structure is seen in the survey image out to ~20 mas from the core, in good agreement with the USNO map at 8 GHz from 1997 Dec. Recommend viewing with mapsize 1024,0.05 and shift -5,5. A HALCA weight of 50 was used for the model fitting. #--------------------------------------------------------------------------- # Do not delete or alter anything past this line {VSOP Survey Checklist and Worksheet version} : 0.3 #---------------------------------------------------------------------------
