Spitzer First Look Survey (FLS) -- NOAO Extragalactic -- R ========================================================== This product contains the R catalogue observed by the National Optical Astronomy Observatory (NOAO) on the fields of the Spitzer First Look Survey (FLS). The catalogue was downloaded from [Vizier J/AJ/128/1](http://vizier.cfa.harvard.edu/viz-bin/VizieR-3?-source=J/AJ/128/1/sources), limited to HELP coverage and separated in one catalogue over ELAIS-N1, and one over xFLS. An `internal_id` column was added to each catalogue to uniquely identify each source as the `Source` column has duplicate values.
