CosmoFit.dataset_reference

CosmoFit.dataset_reference(dataset, version=None)[source]

The citation string for a dataset version, without loading any of its files.

Every registry entry already carries the paper its numbers come from; this exposes it, so a caller that wants to show the provenance – a GUI panel, a figure caption, a log line – does not have to read a 1600x1600 covariance matrix off disk first, and does not have to reach into the private registry to avoid that.

Parameters:
  • dataset (str) – Dataset name, as in available_datasets().

  • version (str, optional) – Which version. Defaults to that dataset’s first registered one – the same default the corresponding load_* function uses.

Returns:

str

Return type:

str
