Technological advancement has led to improvement in the design capabilities of astronomical spectrographs, allowing for high-precision spectroscopy, thereby expanding the realms of observational astronomy. High-resolution spectrographs use echelle gratings that operate in higher orders, giving more detailed spectra. Often, curvature and tilted lines are observed in the spectra, arising due to the design trade-offs of the respective spectrographs. Removal of these artifacts can help avoid wrong…
