Revised Hinode Telemetry Allocations

Following a change to the SOT operating mode, a revised telemetry allocation was agreed by the SWG for Hinode normal mode operation:
			SOT	XRT	EIS							        
Disk Mode		54%	23%	23% 				
Limb Mode		14%	43%	43%  
Previously the EIS telemetry allocation was 15%
SOT XRT EIS
Disk Mode 54% 23% 23%
Limb Mode 14% 43% 43%
Previously the EIS telemetry allocation was 15%

For SP polar observations, the disk mode allocation will be used. However it is possible for an observer to request the higher limb mode allocation for disk observations that would benefit from additional telemetry.

Examples of ways to use the additional EIS telemetry allocation are:

These are just a few examples of how to use the increased EIS telemetry allocation which has significantly extended the instrument capability. The EIS team welcomes inquiries from the solar community regarding the exploitation of the additional telemetry allocation. Team members are happy to provide guidance on the selection and use of appropriate studies to exploit the new capability. Please feel free to consult the team regarding the application of the EIS instrument to particular solar observations. Contacts are:

For the Hinode mission as a whole, the possibility of operating in “focussed mode”, during which commands are uploaded to the spacecraft at weekly rather that two or three day intervals, allows long term studies of evolution in selected targets e.g. coronal hole boundaries, quiet sun network. It is important to make use of this mode as we approach solar minimum.
