  We present an open source software package SpectroLab a Matlab-based tool
developed in 2018 for the analysis of spectroscopic data. In this package,
there are tools for derivative analysis, stacked energy contours, stacked plots
for theory, 3D volumetric plots, core level analysis, and derivative analysis.
The package can currently be used for angle-resolved photoemission spectroscopy
(ARPES) data, with the ability to also be used for other spectroscopic data in
the future. We apply this program to the HfP2, ZrSiS, and Hf2Te2P systems to
demonstrate its robustness.
