COVER INFORMATION Station: VLBA_BR (Code Br ) Experiment: 3.6cm global VLBI observations of the starburst galaxy Arp 220 Exp. Code: gv028b Schedule Version: 2.00 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. EF: Gaps for pointing at: from end of scan 107 at 03:54:29 to beginning of scan 111 at 04:02:12 from end of scan 236 at 08:04:05 to beginning of scan 243 at 08:13:31 Schedule for VLBA_BR (Code Br ) Page 2 3.6cm global VLBI observations of the starburst galaxy Arp 220 UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up. Early: Seconds between end of slew and start. Dwell: On source seconds. Disk: GBytes recorded to this point. TPStart: Recording start time. Frequencies are LO sum (band edge).
