Help Notes

How to Make the First Query

  1. Select the time interval, coordinate range and active regions-of-interest. By default, the entire time period from January 01, 2002 to the present date is set, and all possible coordinates and active regions are included.
  2. Click "Display Instrument-Based Filters". The list of available catalogs and filters will appear.
  3. Select the instrument-based filters. Click the checkbox next to the intrument/catalog name to activate the filters for that instrument/catalog. Then set up the filters of interest. The active filters appear in the "List of Active Filters" field on top of the query form.
  4. Click "Submit" button. The table of events satisfying the selected filters appears. One can scroll the table, sort it based on a particular column, or save the query results to the file.
  5. Select the event of interest from the table, and click the "Plot Data" button. The new page with the event details appears. You can look at the light curve graphs, verify the observational coverage of the selected event, and find similar events.

Questions and Answers

How to select the events from one catalog having no counterparts in other catalog?

This cannot be done directly in the current implementation of the database. However, this search can be done in several steps by 1) querying all the events mentioned in the first catalog; 2) querying all the events mentioned in the first and second catalogs simultaneously; 3) subtracting the results of the second query from the results of the first query.

Is it possible to query the CMEs not associated with the flares?

Sorry, we do not currently provide such an option.

What expansion of the IRIS field of view is suggested to use?

Based on personal experience, we suggest that users expand the IRIS FOV by 100 arcsecs. Positions of the GOES flares are often determined based on the active regions, and use of a smaller expansion may result in loss of some events of interest during the query.
