This service queries the catalog of images from the LOFAR HBA Tier-1
preliminary data release (LoTSS-PDR). This data release contains
images and catalogs that characterise the low-frequency radio emission
in the region of the HETDEX Spring Field. In excess of 40,000 sources
are detected in the images that cover an area of over 350 square
degrees, have a resolution of 25 arcsec, and typical noise levels of
less than 0.5 mJy/beam.

This service queries the unified source catalogue of radio sources
from the Multifrequency Snapshot Sky Survey (MSSS) Verification Field.
This survey is the first major observing program to be carried out
with LOFAR during its ongoing commissioning phase. This service
queries the unified source catalogue database for the MSSS survey. The
Verification Field is a region of 100 square degrees centered at
(15h,69◦).
The The VO @ ASTRON's sitewide SIAP version 2 service
publishes all the images published through the site. For more advanced
queries including uploads, all this data is also available through
ObsTAP.
