To follow up instead of repeating yesterday’s round table discussion…
Access toQuality control of opt/ir imaging
published in the VO
Examples
of
current access
to
quality control
performed by creators
of
publicly available data
Refereed papers
•QC information:•Very thorough…potentially•Very un-standardized•Often most important (but fairly high-level)
README.txt
•QC information:•Thorough nitty-gritty details•Very un-standardized•Close to data itself
On-line data repositories
•QC information:•Linking data exploration→ QC•Very un-standardized
Access to QC info via VO
Uniformize way of access (also look&feel) Link from data to already available QC info
wherever possible Standardize only the easy standardizable
(small) fraction Description (“metadata) is zero order quality
info Description data itself Description data derivation
In VOExplorer/Astroscope
In Aladin

In VO registry
