The recorrelation with 128 channels produced the same answer. Therefore we could question whether the PLS or the data was correct.

All components are part of the core, which is extended in the SW direction (opposite to the PLS direction). Image and Model agree. However vs06u by Horiuchi-san and this do NOT agree. If I apply his very large corrections to all antennae I can reproduce his result (and the PLS), but I don't feel that is justifiable. # 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 #---------------------------------------------------------------------------
