Description:
Effective temperatures are determined for a sample of 165 oxygen-rich
Miras using indices related to molecular band strength of titanium
oxide and vanadium oxide. Using a theoretical evolutionary track on
AGB, absolute bolometric magnitudes are computed. Apparent bolometric
magnitudes are determined from narrow-band photometry observations.
They are used to calibrate distances.
