SoG -- Son of GAIA -- is an extension of ESO
which can display our new HDX/NDX format, as well as FITS and NDF
Using web-service interfaces it can be remotely controlled and
used to display images (as it currently does from Starlink
Treeview). In the fullness of time it is expected to provide
similar features to GAIA (but working within the Grid).
The following image shows it displaying an image of the WMAP
measurements and plotting an astrometric grid overlay.
This second image shows it performing a simple aperture photometry
measurement, but with a twist. The actual measurements are
performed by a "web-service", which could in principle be on
