COVER INFORMATION Station: VLBA_HN (Code Hn ) Experiment: 6cm global VLBI observations of the starburst galaxy Arp 220 Exp. Code: gv028a Schedule Version: 4.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Eskil Varenius Address: Chalmers University of Technology Onsala Space Observatory 439 92 Onsala Sweden Phone: +46706755341 EMAIL: eskil.varenius@chalmers.se Fax: Phone during observation: +46706755341 Observing mode: vlbi Notes: VLA exclude outer 3 stations for each arm. Phase calibrator: J1532+2344 Fringe finder: J1516+1932 Pol. cal.: OQ208 COVER LETTER: This is one of three .key files to observe Arp 220 at 18cm, 6cm and 3.6cm during EVN session I 2023. Arp 220 has two nuclei 1 arcsec apart; we aim to point right in the middle of them, to get both at the same time. OPERATOR NOTES: VLA27: Please exclude outer 3 stations on each arm, to get C-array synthesized beam size.
