QUESTIONS AND ANSWERS
How to select the events from one catalog having no counterparts in other catalog?
We do not allow the user to make the queries like this in the current implementation of the database. However, this search could be done in several steps by 1) querying all the events mentioned in the first catalog; 2) quering all the events mentioned in the first and second catalogs simultaneously; 3) subtracting the resluts of the second query from the results of the first query.
Is it possible to query the CMEs not associated with the flares?
Unfortunately, currently we do not provide such option.
What expansion of IRIS field of view is suggested to use?
Based on personal experience, we suggest the users to expand the IRIS FOV by 100 arcsecs. Positions of the GOES flares is often determined based on the active regions, and usage of smaller expansion may result in loss of some evevnts of interest during the query.
