Visualisation tools used for the visual inspection. Left panel: mosaic tool showing 12 sources in a 3 × 4 rectangular grid. The first object of the second row is marked as a lens candidate, whereas the second object of the third row is marked as interesting. Right panel: one-by-one sequential tool showing an object graded as C. Both tools show a monochromatic high-resolution I_E band image, an H_E Y_E I_E RGB composite image, and a H_E J_E Y_E RGB composite image (in the second row for the one-by-one sequential tool). Both RGB composite images are at the NISP resolution. The one-by-one sequential tool also shows, in its first row, the three NISP bands: Y_E, J_E, and H_E. Users are only required to inspect the high-resolution I_E monochromatic image and the H_E Y_E I_E composite image.
