Plots of model values of structure effects on group delay observables during 24 hr of GMST for two baselines TSUKUB32–WETTZELL (bottom) and NYALES20–TSUKUB32 (upper). The sources are 0016+731 (0.19), 0749+540 (0.38), 1739+522 (0.57), 3C 371 (0.71), and 0642+449 (0.91), where the numbers in parentheses following the source names are the CARMS values calculated from CONT14 observations only. Therefore, these CARMS values should indicate the structure-effect magnitudes of those sources in 2014 May. Five lines represent the model structure delays as a continuous function of GMST based on the image from CONT14 observations (Anderson & Xu 2018a), with the colors indicating the five sources. Filled circles indicate the epochs of actual CONT14 observations. The reference direction within a source image was chosen to be the position of the peak of emission when calculating the mode values.
