Fig. 5:

Correlation structure of the measurement operators arising in deconvolution, super-resolution, and heat-source localization. The left column shows the discrete data $\overrightarrow{\phi }({\theta }_i)$ for three parameter values. The right column gives the absolute values of the corresponding correlation functions ${\rho }_{{\theta }_i}(\eta )=\overrightarrow{\phi }{({\theta }_i)}^T\overrightarrow{\phi }(\eta )$.
