COVER INFORMATION Station: VLA27 (Code Y ) Experiment: 18cm global VLBI observations of the starburst galaxy Arp 220 Exp. Code: gv028c 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 please use all 27 stations at 18cm. 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 use all 27 stations at 18cm.

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) ARP220 117.8 3C286 140.6 OQ208 135.1 J1516+1932 122.6 J1532+2344 118.2 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
