Parameters

hdulHDUList: The HDUList object containing the 2D spectrum.
sn_threshfloat, optional: The signal-to-noise threshold for identifying emission lines. Default is 2.
max_dyfloat, optional: The maximum deviation in the y-direction from the central pixel. Default is 4.
n_erodeint, optional: The number of iterations for binary erosion. Default is 2.
n_dilateint, optional: The number of iterations for binary dilation. Default is 4.
padint, optional: The padding value for the x-limits. Default is 10.
verbosebool, optional: Whether to print verbose output. Default is True.
