Image Details
Caption: Figure 1.
Images of KIDS J0233−3447. Top left: color-composite images (﹩{2}^{{\prime} }\times {2}^{{\prime} }﹩) from KiDS observation and the zoom-in of the lens (12″ × 12″). Top right: Y-band image from HAWK-I@VLT (﹩{2}^{{\prime} }\times {2}^{{\prime} }﹩) and the zoom-in of the lens (12″ × 12″). Bottom: eight-band images from KiDS and VIKING. The two slits used for the spectroscopical observations are shown in orange dashed (for lens) and solid (for arcs) rectangles on the Y-band image, respectively. White arrows labeled with arc1 to arc4 show the approximate location of the regions used to extract the spectra of the arcs (see Section 2.1).
