COVER INFORMATION Station: DSS63 (Code Ro ) Experiment: High-resolution, multi-frequency mapping of the compact sources in M82 Exp. Code: GF019B Schedule Version: 1.00 Processed by SCHED version: 11.40 Release 11.4. March 14, 2015 PI: D. Fenech Address: Department of Physics and Astronomy University College London Gower street, London, WC1E 6BT United Kingdom Phone: +44 (0)20 7679 7682 EMAIL: dmf@star.ucl.ac.uk Fax: +44 (0)20 7679 7145 Phone during observation: +44 (0)7791 563887 Observing mode: Phase-referencing of M82 at 18cm (512 Mb/s) Notes: Lovell telescope missing alternate phase reference scans to keep slewing rate down. Phase-cal is switched off for GF019 observation. Use of a single WSRT antenna required instead of the full array Effelsberg gaps included for pointing checks Schedule for DSS63 (Code Ro ) Page 2 High-resolution, multi-frequency mapping of the compact sources in M82 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).
