find_sed(num, lumclass, interpolate=True)

Find the SED for a star given its numerical spectral type and luminosity class.

Parameters:

• num (float) – Spectral type (e.g., 3.2 = B3.2, 6.5 = K6.5)

• lumclass (int) – Luminosity class (1=I, 2=II, …, 5=V, 6=VI)

• interpolate (bool, optional) – Whether to interpolate between subtypes

Returns:

• (wavelength, flux) tuple

Return type:

tuple

_load_l_t_wd_sed(spec_type, num)

Handle L/T dwarfs and white dwarfs (no luminosity class).

_find_nearest_sed(num, lumclass)

Fallback to the nearest subtype/luminosity class if exact match fails.

_interpolate_sed(num, lumclass)

Interpolate between two nearest templates.

load_sed(sed_file)

Load a single SED file.

_find_closest_template(templates, num)

Find the closest L/T dwarf template (e.g., L5.2 -> L5).
