Excellent photometry and analysis as ever
Many thanks Tony,
The best paper I can find is this one from 1993 and there does not seem to be a modern analysis as far as I can see.
Photometry of EF Pegasi during Superoutburst
The authors say the following in the abstract:
EF Pegasi was observed photometrically during a superoutburst in 1991 October. Superhumps seen during these observations were best fit with a period of 2h .09. This period is used to determine a likely orbital period of 2h .05 and a mass ratio (M_2/M_1) of 0.26. Distance estimates for EF Peg give values of 250 to 600 pc.
Cheers
