Read model-fitting shape estimation papers #8

Open drphilmarshall opened 10 years ago

drphilmarshall commented 10 years ago

Bridle et al started trying to measure shear by fitting blobs; Kuijken et al were not far behind. These days Bridle's method goes by the name Im3Shape and is calibrated to sims to solve the ellipticity prior problem. In between, Miller, Kitching et al applied some clever tricks to their own likelihood-based method, Lensfit, and applied it to the (multi-epoch) CFHTLens data. Lately, Bernstein has got interested in simple model fits, and their limitiations - with Armstrong. Links to follow, @drphilmarshall assigned. Bibtex file to be pushed before this can be closed.

OK, I pushed a bibtex file with the relevant model-fitting methods papers in it, and also a file with all the titles, authors and abstracts of those papers. Probably we should start with Bernstein and Armstrong, and then Zuntz et al's im3shape effort. Kacprzak's papers on biases (with im3shape) will be useful too I think.

did you mean to "close" this?

drphilmarshall commented 10 years ago

Oops - no, we'd better read the papers first.
