Dominion Observatory 10.03 MHz Source Catalog

In the 1960s, the Dominion Radio Astrophysical Observatory in British Columbia, Canada, performed a radio survey of the northern sky at 10.03 MHz, producing a catalog of 124 radio sources, now referenced with the designator prefix DB. The instrument was the Dominion Radio Astrophysical Observatory 10.03 MHz Telescope, an interferometer-array of 400 dipole antennas, arranged in the manner of the Mills Cross Radio Telescope.
