AllStarFit is an experimental R package that includes functions for analyzing optical/infrared images, including:
- object detection and image segmentation using the ProFound package;
- PSF determination using the ProFit package to fit multiple stars in the field simultaneously; and
- galaxy modelling with ProFit, using the previously determined PSF and user-specified models.
AllStarFit supports a variety of optimization methods (provided by external packages), including maximum-likelihood and Markov chain Monte Carlo (MCMC).
