Description
This course introduces advanced usage of Hierarchical Progressive
Surveys (HiPS) and Multi-Order Coverage (MOC) maps in Aladin. Using
this document, you will learn how to handle a problem like : “I have a
set of images. I would like to select regions in my observations that
are above a given threshold in another survey (e.g. at low
extinction), retrieve objects from very large catalogs (e.g. Gaia +
WISE) in these non-trivial shapes and not-necessarily-connected
regions, and combine them to visualise some quantities (e.g. color
color diagram).“
