Light curves of PKS 1749+096 from total VLBI flux density data (filled circles) and single-dish flux density data (open circles, UMRAO data) at 15 GHz. The fitted component ejection time is indicated by the vertical lines, whose length is proportional to the flux density of each component (C4–C7: 15 GHz, C8–C11: 22 GHz) when first seen. Horizontal bars along the time axis denote the uncertainty of the ejection time of each labeled component.
