<dd><p>The HARP Collocation module contains the functionality that deals with collocation two datasets of products. The two datasets are referred to as dataset A (primary) and dataset B (secondary). The result of a collocation is a list of pairs. Each pair references a measurement from dataset A (using the source product name and measurement index within that product) and a measurement from dataset B. Each collocation pair also gets a unique collocation_index sequence number. For each collocation criteria used in the matchup the actual difference is stored as part of the pair as well. Collocation results can be written to and read from a csv file. </p>
