Flowchart compiling our decision criteria to determine the DIB EWs in the upper limit and nonconvergence cases. Part of the spectra analyzed here are those classified as upper limit in our automated method described in EMRL16. The width σ_fit and the depth_fit are the Gaussian parameters derived from the same automated method described in EMRL16. Std_dev is the standard deviation derived from the linear fit to residuals over the wavelength region defined to measure the EW of the DIB.
