In "Simplified" mode, the results in the analysis are calculated by looking at each instrument's mission objectives: for each instrument we keep track of what the primary, secondary, and opportunity mission objectives are. These mission objectives indicate that an instrument is primarily envisioned to measure variable X, Y and Z, that variables A, B and C are its secondary objective, and that it may offer the opportunity to measure variables I and II although it is not optimized for that. The simplified Gap analysis produces a timeline based on this information. The simplified Gap analysis is only available for analyzing variables, not for missions.
In "Expert system" mode, the results in the analysis are calculated with an expert system. Internally, OSCAR works with a large set of 1700 rules that determine whether or not an instrument is capable of measuring a given variable, and to what degree. When you select "Expert system", the Gap analysis is performed based on this large set of rules.

Variable sorting criteria

 

Each instrument is assigned with an up-to-5-step rating, evaluated as a blend of several elements.  For this particular Variable, the rating is driven by:

  • the observed solar area (disk only or disk + corona)
  • the spatial resolution.

 

RATING CRITERIA:

1

  • Disk + corona viewed, high spatial resolution

2

  • Disk only viewed, high spatial resolution

3

  • Disk + corona viewed, coarse spatial resolution

4

  • Disk only viewed, coarse spatial resolution -

5

  • Occultation coronagraph
