... In the observational plane, this relation between physical parameters manifests itself as a correlation between absolute magnitude and colour/spectral type. Those observed relations provide the basis for (spectro)photometric parallax surveys: measure the spectral type or colour of a sample of stars; use those measurements to estimate the absolute magnitude; determine the distance modulus by comparing the inferred absolute magnitude with the observed apparent magnitude. ...
