As a non-lighting engineer, may I ask a simple question in this
thread.

If a lamp is rated at a certain colour temperature then how is its
colour temperature determined from its spectrograph?

A spectrograph of a lamp's emissions seems to show there is a large
and complex number of peaks & troughs sometimes they are in bands
across its spectrum. This seems a tricky starting point.

What analysis is used to create a single colout temperature value
from the spectrum?

This page addresses your question:

Look at sections: The Mathematics of Color (and the corresponding
reference links which point at the algorithms which caluclate the CCT)
The Planckian Locus and Lamp Engineering.
