 Some catalogs have a maximum number of results they will return.
 If a query results in this maximum number of results a warning will be displayed to alert
 the user that they might be getting a subset of the true result set.

 The PanSTARRS catalog also accepts additional parameters to allow for query refinement. These options include column selection,
 sorting, column criteria, page size and page number. Additional information on PanSTARRS queries may be found
