WP2‐040.030.010‐TD‐001
Revision : 1
The interface to the Time Reference is applicable at both phase 1 and phase2 of the project
4.9 Science Computing
The Science Computing provides data and meta‐data reduction to a format desired by the end user
scientist from raw u‐v plane or non imaging data.
The interface to the Science Computing is applicable at both phase 1 and phase2 of the project
4.10 Monitoring and Control
Monitoring includes output from the telescope to the operator. This will provide information on the
health status and the configuration of the telescope and is detailed in the Monitoring and Control
Strategies and Philosophies document [20].
External operator control of the telescope is detailed in the Science Operations Plan [3] and the
Monitoring and Control Strategies and Philosophies document [20] .
The interface to the Science Computing is applicable at both phase 1 and phase2 of the project
4.11 Stakeholders
Within the context of Signal Processing the Stakeholders are the external systems or humans that
interact with Signal Processing equipment. The term ‘interact’ is used to indicate an associated
change of state or the behavioural aspects of the system. The interactions of the Stakeholders are
to be captured using Use Cases which are to be captured as part of the Requirements set.
The Signal Processing Stakeholders include (but may not be limited to):
• Scientists
The Scientist defines and then submits a plan that details the high level usage of the telescope
required for performing observations that support science experiments.
• Operators
The Operator is normally a Staff Astronomer or an Engineer that controls the SKA Telescope during
science experiments or engineering experiments.
• Maintainers
The Maintainer is a technical person that is skilled and qualified prior to receiving SKA Telescope
Technical Training and is responsible for Corrective and Preventive Maintenance and for the
telescope.
The Maintainer is also involved during telescope task execution. The maintainer monitors the system
health displays regularly during task execution and could, when required, takes manual control of
resources for the purposes of testing and diagnosis. (This authorisation needs to be delegated by the
operator).
