Optimisation of the WEAVE target assignment algorithm

Abstract:

WEAVE is the new wide-field spectroscopic facility for the prime focus of the William Herschel Telescope in La Palma, Spain. Its fibre positioner is essential for the accurate placement of the spectrograph’s ∼ 960-fibre multiplex. To maximise the assignment of its optical fibres, WEAVE uses a simulated annealing algorithm called Configure,1 which allocates the fibres to targets in the field of view. We have conducted an analysis of the algorithm’s behaviour using a subset of mid-tier WL2 fields, and adjusted the priority assignment algorithm to optimise the total fibres assigned per field, and the assignment of fibres to the higher priority science targets. The output distributions have been examined, to investigate the implications for the WEAVE science teams.
