If you use these data in a publication, we ask that you please contact us so we can add a link to the list of external MOJAVE publications, and ask that you cite Lister et al., 2018, ApJS, 234, 12 and include the following acknowledgment: "This research has made use of data from the MOJAVE database that is maintained by the MOJAVE team (Lister et al. 2018)"
Important Note: The MOJAVE team, working with the OVRO 40m AGN monitoring team checks and adjusts the flux density scaling of the MOJAVE VLBA data for possible systematics based on near-simultaneous OVRO 40m measurements at 15 GHz. Asterisked entries below denote epochs that have not yet been checked and corrected.
