Description
Interplanetary scintillation (IPS) observations of PKS1148-001 at 326.5 and 102.5 MHz are described. The results from these are combined with published VLBI results at various frequencies to derive a three-component model for the source. The three components have sizes 0.0015, 0.01 and 0.1 arcsec and synchrotron self-absorption below frequencies about 1.5, 0.4 and 0.05 GHz respectively. This model is consistent with the total flux density spectrum. It is suggested that the results of the earlier two IPS surveys made at 327 and 408 MHz at Ooty and Arecibo need to be revised, since PKS 1148-001 is more compact than IPS calibrators used in those surveys.
