You may re-sort the columns by clicking on the headers, or filter the rows using a variety of operators (including ) to select only those objects meeting your criteria. The query page will validate your inputs before performing the search to avoid any errors. By default, Cone Search results are sorted by the angular distance from the query centre. For more complex queries (including cross-matching), we suggest using the SkyMapper TAP service described below. ICRS coordinates (RA & Dec, in a variety of formats) Ĭone Searches from the website are currently limited to a search radius of 1 degree (3,600 arcseconds) and/or 2,000 rows, though larger queries (up to 1,000,000 rows) are possible from other clients.The website currently supports three coordinate options: You may optionally specify how many columns are returned by the service using the metadata verbosity parameter. Performing a Cone Search is the simplest way to query the SkyMapper distilled photometry table ( dr3.master) and requires only a sky position and a search radius. Full Catalogue Search (including TAP access ).Cone Search (including SCS and Multi-object).All three methods can also be accessed through Virtual Observatory-compatible tools such as TOPCAT, Aladin and custom scripts.
We currently provide three ways of accessing SkyMapper Southern Survey data - a simple cone search of the catalogues around a given sky position, arbitrary queries of the full database and external tables using ADQL, and reduced image cutouts with WCS around a given sky position. Data releases are usually made globally available after 12 to 18 months.Īustralian users currently have access to DR3 and all previous data releases. Collaborators residing outside of Australia can also be provided with access to the data. If you encounter errors, try updating URLs to Operations of SkyMapper's Southern Sky Survey were supported by an ARC LIEF grant from 2014 to 2019, which also provides for priority data access to Australian users (persons residing within Australia). The SkyMapper website and services have recently migrated to HTTPS.
