COVER INFORMATION Station: EFLSBERG (Code Ef ) Experiment: Network Monitoring Experiment Exp. Code: N09K2 Schedule Version: 1.00 Processed by SCHED version: 8.00 2008 December Release PI: Stefanie Muehle Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: muehle@jive.nl Fax: +31-521-596539 Phone during observation: +31-521-596508 Observing mode: Notes: Please do NOT use the phase cal signal. Thanks. Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for a short K-band experiment to test a wide-band mode requested in a EVN proposal. The goal is to achieve a bandwidth of 256MHz by using 16 channels (8 BBCs with LSB and USB) with 16MHz filters in one polarization (LCP). Please double-check the setup at your station and send any updates to the catalog files to JIVE. Thanks! Please check in your rxg-file whether you have measured Tcal values for the whole 256MHz wide frequency range. Ef: Please note the long slew time between scan #3 (4C39.25) and scan #4 (J1642+68). If possible, please check if a different topo at the start of this schedule can avoid such a long slew. Thanks! Good luck!
