the appropriate `astropy.coordinates` object. ICRS coordinates
may also be entered as strings as specified in the

`astropy.units` may also be used. When missing defaults to 1
arcmin. Cannot exceed 90 arcmin.
programme_id : str

database : str
The UKIDSS database to use.
get_query_payload : bool, optional
