#### 6.1.3 `addresolve`

Usage:

       addresolve <col-id-objname> <col-name-ra> <col-name-dec>

Performs name resolution on the string-valued column `<col-id-objname>` and appends two new columns `<col-name-ra>` and `<col-name-dec>` containing the resolved Right Ascension and Declination in degrees.

Syntax for the `<col-id-objname>` argument is described in Section 6.2.

UCDs are added to the new columns in a way which tries to be consistent with any UCDs already existing in the table.

Since this filter works by interrogating a remote service, it will obviously be slow. The current implementation is experimental; it may be replaced in a future release by some way of doing the same thing (perhaps a new STILTS task) which is able to work more efficiently by dispatching multiple concurrent requests.

This is currently implemented using the Simbad service operated by CDS.
