GCR v0.9.2

The v0.9.2 release contains a minor improvement in the behavior of get_quantity_info(), which now works better for composite catalogs and for quantity aliases (#36).

GCR v0.9.1

This is a bug-fix release. A bug in the composite catalog class has been fixed (#34).

GCR v0.9.0

GCR v0.9.0 presents a much improved CompositeCatalog class.

Now each catalog of the composite can have its own fine-tuned settings, defined by CompositeSpecs. In particular, one can specify whether each of the composite component:

• has matching partitions as the main catalog (matching_partition)
• has the same row ordering as the main catalog (matching_row_order)
• uses one column to match to another column in the main catalog (matching_by_column and matching_column_in_main)
• should overwrite existing columns in the main catalog (overwrite_quantities)
• should overwrite existing catalog attributes in the main catalog (overwrite_attributes)
• should include native quantities (include_native_quantities)

In addition, now matching_partition and matching_by_column can be set at the same, to speed up index matching if the partition is the same among catalogs (cf. LSSTDESC/gcr-catalogs#398)

Also, get_quantity_info method would now properly propagate (cf. LSSTDESC/gcr-catalogs#410)

While this update significantly changes the implementation of CompositeCatalog, I have tried my best to preserve backward compatibility with 0.8.x. Please note that CompositeCatalog is still an experimental feature, and its API is not fully stable.

GCR v0.8.9

Add always_return_masked_array option for composite catalogs that are matched by columns.

GCR v0.8.8

This is a bug-fix release to fix an issue in composite catalogs that match order.

GCR v0.8.7

This release fixes a bug where concatenate_1d does not work with masked arrays (#25).

GCR v0.8.6

This release fixes a bug about concatenating arrays that was introduced in 0.8.5 (#24).

GCR v0.8.5

• Bug fix: now returns a empty ndarray when native filters have no matches (#22, #23)

GCR v0.8.4

This PR:

• adds a feature that allows composite catalog user to access the attributes of underlying catalogs directly (#21)
• minor bug fix and improvements (#20)

GCR v0.8.3

Bug fix release
