Imaging over 3,000 Quasars that are a part of the International Celestial Reference Frame
Abstract
We present simultaneous VLBA 2 GHz and 8 GHz images of over 3000 quasars that comprise the the third realization of the International Celestial Reference Frame (ICRF). These images are important in determining how source structure affects the determined position and allow us to correct those positions and improve the accuracy of the ICRF. We present the distribution of peak flux, and source structure in the images. We will make these images publicly available to the astronomical community as part of the USNO Fundamental Reference Image Data Archive (FRIDA).
