Starlink::ATL::Region - Tools for AST regions.


  use Starlink::ATL::Region qw/merge_regions/;

  my $cmp = merge_regions(\@regions);


This module contains a utility subroutine for working with AST regions.



Takes a reference to an array of AST regions and returns a single CmpRegion object. The CmpRegion is built in a tree manner rather than linearly to minimize the depth of the structure.
