The observation component editor is accessd by selecting the observation component in your science program, and is shown below.

The relative priority of this observation, compared with other observations in the same science program, is set using the High/Medium/Low buttons. See more details on how the priority affects execution and to add observations into groups. If not already defined, you can edit the observation name to make the science program viewer more understandable (normally this will be the science target name). 

The Save button accepts the latest changes and stores the program to the local database,  and the Close button closes the science program editor (saving any changes to the local database).

The observation status indicates the state of the observation through preparation and exectution. The status can have the following values. These values determine the color of the observation icon.

• Phase 2 - The observation is in Phase 2 preparation. This is the default when the observation is created.
• For review - The PI has finished the Phase 2 preparation and the observation is ready for review by NGO staff. The result of review is "For activation" or back to "Phase 2" for more work.
• For activation - The observation has been successfully reviewed by NGO staff and it is ready for final review by Gemini staff. The result is "Ready" or "On hold", or back to "For review" for further changes.
• On hold - The observation has been 'verified' but is not to be queued, e.g. it is waiting to be used as a TOO trigger.
• Ready - The observation has been 'verified' and is ready to be scheduled/executed.
• Ongoing - Execution is in progress.
• Observed - The observation has been executed.
• Inactive - The observation is not needed, has never been executed, and should not be queued.

The QA state is set by Gemini staff after Quality Assessment of any data taken (see more details of the QA process). The values are:

• Undefined - no data taken or data not yet assessed
• Pass - The quality assessment has been performed on the data. It meets the science needs and has therefore passed QA. The time used is charged to the program.
• Usable - quality assessment has been performed on the data. It does not meet the PI's science needs but might be usable by someone else (via the archive). The time is not charged to the program.
• Fail - The quality assessment has been performed on the data. It has failed QA and will not be archived. The time is not charged.
  

The Observing Time table gives all of the time charges for the observation. Different times are charged to the program or to the partner based on the observation class and the Quality Assessment.

The Time Correction Log is used by Gemini staff to make adjustments to the automatic time accounting based on the QA of the individual datasets.
