Mosaicking

The VLA supports mosaics that use a discrete pointing pattern with pointing centers that are set up as individual fields to be observed (as if they were just a set of target sources).

For more information on setting up mosaicking, please see the section on Mosaicking and OTF in the Guide to Observing.

On-The-Fly Mosaicking (OTFM)

OTF mosaicking eliminates the slew and setup overheads and thus is useful for shallow very large mosaics. OTF mosaicking with the VLA is currently offered under the SRO program only.

For more information on setting up on-the-fly mosaicking and various practical considerations to request observing time in this mode, please see the On-The-Fly (OTF) Mosaics subsection in the Mosaicking and OTF section of the Guide to Observing.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
