Abell 3827 (z=0.099)

Image identifications and nulls for GRALE

z=0.204 sources:

Blob 1 images  and  Blob 1 null
Blob 2 images  and  Blob 2 null
Blob 3 images  and  Blob 3 null
Blob 4 images  and  Blob 4 null

z=0.408 source:

Arc images  and  Arc null



Images used and corresponding reconstructions
squares: galaxies
filled dots: lensed images
empty dots: bright specs in HST images (not used as GRALE input)
small magenta dots: GRALE reconstructed sources lensed thru the mass maps (compare these to filled dots for lens-plane error)
small green dots: GRALE reconstructed sources in the source plane
small empty black circles: local density peaks
images used in each reconstruction are marked in each panel
note the arcsec scale in each panel

Note: The upper right mass concentration is representing shear from the mass outside the GRALE frame, but in that same direction
