Analysis of observed and deconvolved ellipticities of globular clusters in M31.
Abstract
From five models of globular clusters the authors found a strong correlation between mean ellipticity of observed and deconvolved (by two methods) images. Also a relationship between true and convolved ellipticity can be derived from models. Data on 13 globular clusters in M31, observed by the FOC f/96 of the Hubble Space Telescope, confirm the observed - deconvolved relationship.
