RCU Modes/Bands

The RCU mode (now configured via the --band flag) allows you to set the observing window for a given set of RSPs / RCUs. While these can be applied selectively to specific antenna (allowing for configurations such as KAIRA's Mode 3-5-7), the array is often kept in a single observing mode, depending on the target.

Mode 0, 1, 2

These modes are the OFF, Low-band Low (200MHz) and Low-Band Low (160MHz) observation modes, they should not be be used on international stations and are meant to selectively use different parts of the array in the core and remote stations.

Mode 3 (10_90)

Mode 3 is the standard LBA observing mode, using the entire set of LBA antenna and the 200MHz clock. 

Mode 4 (30_90)

Mode 4 enables observation with the entire set of LBA antenna and the 160MHz clock. 

Mode 5 (110_190)

Mode 5 is the standard HBA observing mode, enables observing with the HBA tiles and the 200MHz clock.

Mode 6 (170_230)

Mode 6 enables observing with the HBA tiles and the 160MHz clock.

Mode 7 (210_250)

Mode 7 enables observing with the HBA tiles and the 200MHz clock. It has a reduced bandwidth compared to the other modes as a result of significant amounts of RFI and antenna attentuation being present above ~240MHz.
