Cross Identifications
This page provides an interface for dynamic cross identifications of FIS or IRC objects with a user defined list of object positions. The positions (lon,lat) of user's list can be set by J2000, B1950, Ecliptic or Galactic coordinate.
For each position in your upload list, this tool can search not only a nearest object but also all nearby objects. If you want to obtain the list of all nearby objects, set "All nearby objects" at the Search scope selector.
You can select version of FIS and IRC catalogs by Database selector. Default setting is for latest version of catalog set.
The `#result' argument in SQL statement is replaced with
fGetCrossIdResultEq() function which will perform the cross identification
and return a table of result.
This table includes the following information.
| name | type | description |
|---|---|---|
| id_x | INT4 | Sequential ID of uploaded target position. |
| name_x | VARCHAR | Name of uploaded target position. |
| ra_x | FLOAT8 | R.A.(J2000) of uploaded target position. |
| dec_x | FLOAT8 | Dec.(J2000) of uploaded target position. |
| seqNo | INT4 | Sequential number of uploaded target having found object(s). SeqNo of last row indicates total number of target positions which have found object(s). |
| objCount | INT4 | Count of found object(s) for each uploaded target position. |
| distance | FLOAT8 | Distance (arcmins) between (ra_x, dec_x) and found object. |
| objID | INT4 | Object ID of found object. |
See the SQL schema page to find out more about structure or function of the SQL.
