The diagrams show a 12 order polynomial fit to the mean lightcurve at maximum. The lightcurves is based on data from AAVSO, AFOEV, VSOLJ, BAAVSS, ASAS-SN and DASCH. The lightcurves covers 80% of the period around the maximum.
For each individual maximum a 8 order polynomial was fitted and the time for the maximum was established. Each individual maximum was centred with the time for maximum as 0 and then overlaid on each other. Finally a 12 order polynomial fit was made based on the overlaid curve and using observations within of 80% of the star's period around maximum.
The mean lightcurves was then overlaid and best fitted to each identified individual maximum for the star and once again was the time for maximum and magnitude at maximum recorded. This data together with O-C diagrams for the selected Miras can be found at O-C diagrams for Mira stars.
The period elements and spectral type under each diagram is from GCVS4, the magnitude at max is from the calculated maxima.
