I know; however casacore in the moment provides a table with ICRF1; see f.e. ftp://ftp.astron.nl/outgoing/Measures/WSRT_Measures.ztar If there is no reason to stay with ICRS1, I would use ICRF2; I will however see if some arguments pop up upstream: https://github.com/casacore/casacore/issues/539 Cheers Ole
