Write a brief summary of the data reduction and its outcomes} : PLS radplot of source (J0132-16) showed flux decreasing to approximately 0.5Jy at 140Mlambda. No AT light curves. Uncorrected (using only ANTAB values) amplitudes had a flux at 150Mlambda of about 250mJy (Hh-Aus baseline). Low spacing flux was about 0.5Jy. Both of these flux values are about half of the PLS flux. Flux for calibrators was about 60% of the PLS flux for J0204+15, and about 85% of the PLS flux for J0106-40. No fringes were found to Ho or Halca. Hard to say whether any any space fringes should have been detected or not. However, this experiment was one of three observed around the same time (VS06h, VS07s, VS08c), with only one tracking station (Uz), and all with failed space fringes. I suspect whatever caused the lack of space fringes was not source intrinsic but instead was due to a tracking station problem (???). #--------------------------------------------------------------------------- # 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} : Flagged out Hobart and Hart, as they had no fringes (makes sense, since did not get FRING solutions for these antennas. Very difficult to get a good clean component model, so used an elliptical Gaussian for the core, and model-fit the extended emission with clean components. Tried and amp self-cal for fun, but it gave corrections to Hart of about 1.9, which I did not believe, and so disregarded. # If GSCAL was used, report amplitude correction factors here. If GSCAL # was used more than once, report the CUMULATIVE factor here (e.g if gscal # reported a gain factor of 1.11 for HALCA the first time and 0.95 the # second time, the overall gain correction is 1.11 * 0.95 = 1.05. # Separate antenna names and correction factors by commas or spaces. # e.g # # {Antenna name list} : HALCA, HO, HH, MP, KA # {Amplitude correction factors} : 1.0, 1.6, 1.3, 1.0, 1.0 # {Antenna name list} : {Amplitude correction factors} : #------------------------------------------------------------------------- # Do not delete or alter anything past this line {VSOP Survey Checklist and Worksheet version} : 0.4 #-------------------------------------------------------------------------
