The K band and the Q band single-frequency single-polarization modes are available and a recording rate of 1024 Mbps (total bandwidth of 256 MHz) will be open for the 2016A CfP. Dual-beam mode with VERA, dual-polarization with KVN, and simultaneous multi-frequency mode with KVN will not be available for the 2016A CfP. For accurate astrometric observations, many items (antenna positions, calibrators, schedule, etc.) should be carefully considered and prepared. At present, astrometric VLBI observations with KaVA is not supported in the 2016A CfP. Moreover, phase-referencing based on antenna-fast nodding with VERA and KVN has not yet been available in the 2016A CfP, since the feasibility of the phase-referencing observation including scheduling, recording, and correlation, should be fully verified.
