Fig. 8.


Time delays for the LBA stations assuming that ϕ0 = 0. The time delays obtained from holography observations are shown for two orthogonal polarizations (XX and YY). We also show the time delays derived from imaging observations for Stokes I. During the calibration of imaging observations the phase offset between XX and YY polarizations is removed by assuming that a reference station has zero phase offsets (de Gasperin et al. 2019). The time delay for CS401LBA is 0 because this station was used to reference the phases. Station CS031LBA is missing in the imaging data because it was completely flagged.
