Here is a list of all AGN monitored at OVRO. Only the data of sources from the CGRaBS sample are made public on this website. If you wish to obtain data for other sources, please contact us via email.
Please be aware some data points observed before May 2014 appear in the current data release that had been flagged out in previous releases. This happened due to changes in the data reduction scripts and will be fixed as soon as possible. For questions please contact us via email.
When using data from the OVRO 40m program, consider the data usage policy shown below.
Data Usage Policy
These data are being made available to the public as a service to the astronomical community. Please remember that the collection and processing of these data represent a major effort. While we encourage open sharing and use of these data, publications using data of more than one source are not permitted without prior approval and a proper attribution. Please email us with a brief description of your project in case you are interested in using data of multiple sources. For single-source papers, please include the following acknowledgment: "This research has made use of data from the OVRO 40-m monitoring program (Richards, J. L. et al. 2011, ApJS, 194, 29) which is supported in part by NASA grants NNX08AW31G, NNX11A043G, and NNX14AQ89G and NSF grants AST-0808050 and AST-1109911." We also request that you inform us via email with a brief description of your project or publication so that we may keep track of the impact of our work.
Note that the data since June 1, 2014 are taken with a new receiver and should be considered preliminary. Between Aug 1 and Nov 24, 2015 the receiver was not working optimally, and the noise in the data is higher during this period. Any variability analysis using data over that period (especially in sources less than about 200 mJy in brightness) should be done with extra care. Therefore, it is highly recommended that you contact us before using these new data in any analysis so that we can check the quality of the final light curve.
