skyregion

Defines possibly complex sky region (including STC-S regions) and test if a point on the unit-sphere is inside or not. Also provide B-MOC like coverage to quickly retrieve (and possibly post-filter) indexed sources?

About

This Rust library was originally part of the QAT2S code but is now independent to be used elsewhere.

Supported regions

• Cone
• Ring
• Elliptical Cone
• Multi-Cone
• Polygon
• Box (see one of the Polygon constructors)
• Zone
• JName (see one of the Zone constructors)
• STC-C (including complex STC-S with multiple union, intersection, ...)
• HEALPix:
  • single index
  • index range
  • set of (sorted and non-overlapping) ranges

Features

You may activate the rayon feature to benefit from parallelism in the multicone region. To do so, add in you Cargo.toml file:

skyregion = { version = 0.1.0, features = ["rayon"] }
