Demands on the working catalogue when determining the astronomical refraction and influences of systematic error of the catalogue are related. And the systematic error of the FK5 with respect to Hipparcos Catalogue is put forward so as to explain why all the earlier star catalogues are inapplicable to refraction measurement. The characteristic of …
