The OVRO 40 m Telescope is providing a service to the astronomical community: Since 2008 over 1,500 blazars have been monitored on a ~3-day cadence at 15 GHz. Since January 2021 over 5,500 blazars have been monitored on an 11-day cadence. Caltech thanks the hundreds of astronomers worldwide who have contacted us, in accordance with our data usage policy, leading to an average of over one paper per month in refereed journals using 40 m Telescope data since 2008.
Unfortunately, we have learned recently of several violations of our Data Usage Policy in which people have downloaded data for a single source without informing us, downloaded data on multiple objects without prior permission, and/or neglected to include acknowledgments to our sponsors (see below).
If you have used OVRO 40 m Telescope data for any purpose, including both studies of radio lightcurves and publication of results derived from the lightcurves, without prior permission, please contact Sebastian Kiehlmann as soon as possible to discuss how to comply with our Data Usage Policy.
Acknowledgment to be included in all publications using 40m Telescope data:
"This research has made use of data from the OVRO 40-m monitoring program (Richards, J. L. et al. 2011, ApJS, 194, 29), supported by private funding from the California Insitute of Technology and the Max Planck Institute for Radio Astronomy, and by NASA grants NNX08AW31G, NNX11A043G, and NNX14AQ89G and NSF grants AST-0808050 and AST- 1109911."
