1D example of the automatic component modeling method. The top panel displays the background b (in blue) and the total signal s (in orange) which is the superposition of the background b and the foreground line f signal components. The bottom panel shows the signal response (solid green line), obtained by convolving the total signal s with a Gaussian PSF. Additionally, it displays a synthetic data realization of the signal response (in red), along with the 2σ shot noise level contours associated with the background (dotted green lines). In both panels the vertical dashed-dotted gray lines represent the ground truth line component f locations. We note that a large fraction of the line signal f is buried beneath the background noise level.
