Core Community Survey · High Latitude Wide Area Survey
Medium Tier
Dark energy, via weak lensing and galaxy clustering
What this is
Three-band imaging plus grism spectroscopy. The colours give photometric redshifts; the grism gives spectroscopic ones for the clustering measurement.
Four nested tiers over more than a tenth of the sky. Wide tiers supply the galaxy shapes weak lensing needs; deep tiers calibrate them and reach the earliest galaxies.
