dc.description.abstractMultiwavelength Very Long Baseline Array observations of a sample of 49 extragalactic radio sources selected from the Micro-Arcsecond Scintillation-Induced Variability survey are presented. These observations are intended to provide a sizeable, uniform data set for the investigation of angular broadening of scintillating sources. These data will be used to compare and contrast the scattering behavior of scintillating and nonscintillating radio sources in subsequent analysis. We confirm earlier analyses that found scintillating sources to be more core-dominated than nonscintillating sources.en_US
