Re: HD 116274

Finally got the other minimum, presuming this is an EW or similar. See:

I've also made the data available if anyone wants to play with it here:

The minimums are very near equal and this thing still phases fine at 
half of the period. I'm assuming a period of about 0.605d right now. 
The ASAS-3 data does not phase at half the period so this is probably 
an EW. The eclipses look pretty flat to me. Might the inclination be 
near 90?

Cheers,
