Conditions for use of data in publications
Note there is no a complete validation check prior to adding spectra to this table. Users should verify the quality of the spectra with the observers concerned.
Use of these data in research publications is encouraged (with citation or association of observers concerned).

V magnitude (source AAVSO) and spectrographic observations timing.

Time serie evolution. The spectra are shifted by 1.0 unit along intensity axis for clarity reason (first epoch)

Time serie evolution. The spectra are shifted by 1.0 unit along intensity axis for clarity reason (second epoch).

Dynamic time evolution evolution spectum (T94 Saint-Caprais data only).
