Observation of Kardar-Parisi-Zhang universal scaling in two dimensions

Data set used in the publication "Observation of Kardar-Parisi-Zhang universal scaling in two dimensions", including power series data, hyperspectral images, real space tomographies and Michelson interferometry data for square as well as triangular polariton lattices. A detailed desciption is available in a text document. A data set which is already interpolated to constant condensate output power is available upon request from the corresponding authors.
