VLBA Astrometry of Compact Radio Sources in the Spitzer First-Look   Survey
  The NRAO Very Long Baseline Array (VLBA) was used at 1.4 GHz to image 20 compact sources in the inner 1-degree radius of the Spitzer VLA First-Look Survey. Twelve sources were detected with the VLBA, with peak flux densities above 2 mJy at 9-mas resolution. The positions of these VLBA detections have been measured in the International Celestial Reference Frame (ICRF) to 1-sigma accuracies of 8 mas East-West and 4 mas North-South. These positions can help anchor ancillary data for the First-Look Survey to the ICRF and are being reported quickly to the community.
