#### Description:

This attribute gives the indices of the longitude and latitude coordinates of the FITS-WCS projection within the coordinate space used by a WcsMap. These indices are defined when the WcsMap is first created using astWcsMap and cannot subsequently be altered.

If `"` lonlat`"` is 1, the index of the longitude axis is returned. Otherwise, if it is 2, the index of the latitude axis is returned.

Type:

  Integer, read-only.
