(*) HiPS is a recommended International Virtual Observatory Alliance standard:HiPS REC. The HiPS technology allows a dedicated client to access an astronomical survey at any location and at any scale. HiPS has been invented by CDS-Université de Strasbourg/CNRS (2015A&A...578A.114F). It is based on HEALPix sky tessellation and it is designed for astronomical scientifical usages (low distorsion, true pixel values...).
