How do I search for data using catalogs?
These instructions assume that you are using the VSO Web Interface. If you are using some other VSO interface, you should consult its documentation.
Go to the VSO Search Form -- your organization may have a local VSO instance, or you can go to the Virtual Solar Website, and follow the link to search for data from there.
Under 'Time' there should be a link labeled Derive time intervals from event catalogs. You should follow that link.
You should select the time period of interest (or 'Whole Catalog'), which catalog to use, and the parameters for searching that particular catalog, and then click the 'Search' button.
You can then select specific events within the catalog that are of interest. You can then either perform a cross-catalog query, or search for data products.
Cross Catalog Queries
After selecting the events of interest, press the button in the left toolbar labeled 'Cross-Catalog Search'. This will present you with the catalog search page, where you can choose new parameters to search on, using the time ranges of the given events. Time windows can be modified using the 'Match Criteria' field.
Search For Data Products
After selecting the events of interest, press the button in the left toolbar labeled 'Search for Data'. This will present you with the VSO search page, where you can specify how to adjust the time windows, and other parameters. (see HowToSearch for more details on searching for data using VSO)
