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 group, discovered a systematic error in the flux densities of all VLBA 15 GHz observations taking place after a date that lies between 2019 April 16 and 2019 May 16. Observations after that date have correlated flux densities that are between 10% and 20% too low. We have adjusted the flux density scaling of the MOJAVE VLBA data up to 2022 Jan 3 based on near-simultaneous OVRO 40m measurements at 15 GHz.

Asterisked entries below denote epochs that have not yet been corrected for the VLBA flux density scaling problem.
