Solar / Stellar Flare Comparison SD

Introduction

An astronomer wants to compare solar and stellar flare activity. After identifying solar and stellar flare datasets with similar properties, the astronomer can then analyse and compare the data online.

Flow of Events (Revised)

1. First, the astronomer searches the resources catalogue for solar flare catalogues via PerformRegistrySearch.

2. A list of solar flare catalogues, such as the Trace Flare Catalogue and Hessi Flare List, is returned to the astronomer and MySpace via MySpaceStoreResults.

3. Next, the astronomer selects one or more catalogues via SelectCatalogue to query for flares by intensity, duration, and morphology if available via PerformCatalogueSearch.

4. A list of flare names and times matching the intensity, duration, and morphology parameters is returned via MySpaceStoreResults.

5. The flare names and times are entered into a complex query of the resource catalogue to search for solar red / blueshift data and lightcurves matching the flare times or flare names via ComplexQuery.

6. Red / blueshift datasets and lightcurves of solar flares are returned to the astronomer and stored in MySpace via MySpaceStoreResults.

7. Now the astronomer performs a literature on stellar flares via PerformLiteratureSearch.

8. The astronomer has acquired stellar flare times and positions from the literature search.

9. The flare times and positions are entered into a complex query to search the resource catalogue for red / blueshift data and lightcurves covering the stellar flare times and positions via ComplexQuery.

10. Red / blueshift datasets and lightcurves of stellar flares are returned to the astronomer and stored in MySpace via MySpaceStoreResults.
