资源简介：
We have undertaken an exploratory Q-band (43 GHz) imaging-astrometry project targeting the K- band ICRF sources in three sessions each of 24 hours using the Very Long Baseline Array. The project’s goal is to compare images and astrometry from X, K, and Q- bands in order to study the optimal frequency band for CRF observations. The sources were observed as close as possible in time, typically within a week, in order to minimize temporal variations in source structure. We will show how source structure compares between all three bands, and the interplay between source structure, resolution, and astrometry. We hope to use the results from our campaign to determine if pursuit of a Q-band CRF is worthwhile.
