Purpose
=======
The purpose of this experiment is to determine station coordinates and their
evolution in the southern part of the European geodetic VLBI network with the
highest precision possible.
Schedule
========
The schedule was optimized for local sky coverage. Scans are scheduled to have
scan length purely according to SNR limits.
The sky coverage for all stations were optimized.
The minimum SNR on all baselines at X/S-band are set to 24/22.
Comments
========
A new freq setup mode are used in this EURR&D.
Beginning with 2017 we will observe alternating in different frequency setups.
The named EURR&D-xx will observe with 512Mbps and wide band (CONT11 setup).
There are no observations for Wettzell from 18:20 U.T.
to 19:40 U.T. Wettzell will participate in the
intensive session during this 1.5 hour period.
