Estimate the temperature and luminosity of the stars

Script to calculate the temperature and luminosity of the stars.

You should know: - spectral type in number (see the conversion table below), - extinction, - distance, - V or J magnitude of the star.

Use the standard values, like Kenyon and Hartamann 1995.

For information to estimate the spectral type, can see this web page: http://www.cida.gob.ve/~hernandj/SPTclass/sptclass.html
