(Mitaka/Penticton/Socorro)} : Mitaka {AIPS Version used (e.g 15OCT98)} : 15OCT99 {Difmap Version used (e.g 2.3c)} : 2.3c {Was vsop_difmap used? (yes/no)} : yes {Abstract. Write a brief summary of the data reduction and its outcomes} : This experiment consists of Arecibo, Greenbank and Hart. Real time Tsys information was only avairable for Hart. Nominal values of DPFU and Tsys are applied to GB. Any SEFD values for AR at C-band is not known and I adopt DPFU=1 and Tsys=10 K. With fairly good fringes for both Madrid and Usuda pass, I checked the cross points in uplot of difmap and found that SEFD is appropriate for both HA and AR regarding with USNO visibilities at both S and X band. However GB baselines provide too low amplitude about 1/3 of the expected valuse and correction with CLCOR in AIPS realize reasonable radplot in the end. #--------------------------------------------------------------------------- # Section 2 : Pre-AIPS Checklist #--------------------------------------------------------------------------- {PI letter retrieved (yes/no)} : yes {Data quality reports and plots retrieved?

After GSCAL correction, clrmod true is applied and start with the new clean compornents. The image shows source elongation toward SW direction and this agrees with VLBA 15 cm survey image. Two gaussian model fit was performed with self-calibrated data. # 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} : ARECIBO, NRAO_140, HARTRAO, VSOP_SC {Amplitude correction factors} : 1.13, 1.54, 1.53, 0.72 #--------------------------------------------------------------------------- # Do not delete or alter anything past this line {VSOP Survey Checklist and Worksheet version} : 0.4 #---------------------------------------------------------------------------
