Colour composite image (Red = NISP J_E + Y_E + H_E, Green = HST-ACS-F850LP, Blue = VIS I_E) of the central region of A2390. The circles mark the position of the spectroscopic sample of SL constraints from Richard et al. (2008, 2021) colour coded by their spectroscopic redshift (indicated in the upper left). The number next to each small circle is the ID for each family of counterimages. We show the critical curves from the SL + WL model in cyan at z_s = 1.036 and red at z_s = 4.05. The image covers $1\stackrel{\prime }{.}73\times 1\stackrel{\prime }{.}18$.
