COVER INFORMATION Station: MEDICINA (Code Mc ) Experiment: How do O-type forming stars accrete their mass? Exp. Code: EG073B Schedule Version: 2.00 Processed by SCHED version: 11.40 Release 11.4. March 14, 2015 PI: Ciriaco Goddi Address: Radboud Astronomy Department Heyendaalseweg 135, 6525 AJ Nijmegen Netherlands Phone: +31 243652845 EMAIL: goddi@astro.ru.nl Fax: Phone during observation: +31 243652845 Observing mode: Polarimetric observations in phase-reference of 1 maser so Notes: There are two sources ~1arcmin apart in the sky. We observe at an intermediate position. At correlation, we require two passes at each source position. This is a multi-epoch experiment. This is the second epoch; next in 2yr Phase-cal OFF Schedule for MEDICINA (Code Mc ) Page 2 How do O-type forming stars accrete their mass?
