Simply hover your cursor above the QUERY button in the header to access the query form.
At the moment, you are able to constrain the query by name strings, ranges of coordinates, ranges of available properties. There is a switch to toggle coordinates from degrees to hour angle and vice versa. Furthermore, you can check/uncheck object classes as needed. Note that the processing time of your query scales with the number of found matches. It is possible to drop the entire database but writing the table will take a while.
The form allows you to check/uncheck table columns that you are interested in. The table delivers all known name aliases as well as a list of all measured properties with the corresponding reference links.
An export of your specific query results to a text file is available as well.
Give more visibility to your publication by sending us the value of your measurements and the reference! They will be added to the database and your work will not be missed in statistical studies.Get In Touch
