F. Beck. (2017)cite arxiv:1707.05973Comment: 31 pages. Streamlined exposition and minor fixes. The proof of the main result got simplified and now only uses the theory of variations of (mixed) Hodge structures instead of (mixed) Hodge modules.
E. Rains. (2013)cite arxiv:1307.4033Comment: 98 pages LaTeX. v2:Sections added on limit relations, singularities, Calogero-Moser spaces, also minor terminology change. v3:typos.
D. Alessandrini, G. Lee, and F. Schaffhauser. (2018)cite arxiv:1811.05366Comment: 40 pages. v3: Expanded version: now includes an alternate expression for the dimension formula and an extension of the main theorem to the case of orbifolds with boundary.
