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.
