Value Members

1. object CenterCrossMatch

   

   Object containing routines to perform cross match between two sets A & B based on the position of object centers.

2. object PixelCrossMatch

   

   Object containing routines to perform cross match between two sets A & B based on an underlying pixelisation.

   Object containing routines to perform cross match between two sets A & B based on an underlying pixelisation. The space is first pixelised, and match is done between cells of this pixelisation. As a first example, we include the Healpix pixelisation (2D pixelisation). Each RDD partition is a shell, projected on a 2D plan, and pixelized.

3. object RangeQuery

   

   Handle range query, including window query.

   Handle range query, including window query. Note that window query is just a sub-case of CrossMatch, just one of the two data sets has only one (extended) element... ;-)

4. object SpatialQuery
