This input field must contain either a sky coordinate or an object name resolveable via IRSA, NED, SIMBAD, or SWAS. 2MASS or SWAS object names are resolved by IRSA while all other names are resolved via NED/ SIMBAD). This coordinate or object name corresponds to the position to be searched for all search modes of RADAR.

If the input field contains a string which can be interpreted as a coordinate representation, it is used as such: both decimal degree and sexagesimal notations are supported. If not, the string is sent first to IRSA of 2MASS resolver, then to NED, to SIMBAD, and finally to IRSA's SWAS resolver to attempt name resolution. The following are examples of acceptable name formats:
