Map of the Gaia RR Lyrae stars satisfying the selection criteria 1 and 2, zoomed in on the stream arm around the GC NGC 2419. The RR Lyrae variables belonging to the cluster are highlighted in blue. The red square indicates the mean distance of these RR Lyrae if the metallicity of the cluster is assumed ([Fe/H] = −2.09; after Mucciarelli et al. 2017), instead of the mean metallicity in the stream, [Fe/H] = −1.3.
