    Research output: Contribution to journalArticlepeer-review


    We observed 630 sources with the LOFAR international baselines to determine if they are compact enough to be delay calibrators. We used information in other catalogs to determine their properties. The quality factor (q) is a measure of they reliability of the source as a potential calibrator. q=3 indicates good primary calibrators, q=2 indicates potentially good primary calibrators, and q=1 indicates sources that are resolved or faint or both. All WENSS peak flux densities in this paper include a correction factor of 0.9 with respect to the original catalogue to place them in the RCB scale. (1 data file).
