Rich, No, setting periodicity=0 is what turns it off. Removing the setting sets periodicity checking to its default value of 1. Periodicity checking is always relevant with inside pixels because it determines whether or not we can bailout early, or if we have to wait until maxiter is reached. This is done by comparing orbit values. If the orbits are at the same point or are converging on a point, then the orbits will never escape and we can claim victory and bailout early. In this par, with periodicity=0, no periodicity checking is done and all the inside pixels should have all maxiter (90) orbits calculated. For some reason, the bailout value is reached (or an overflow occurs) after two iterations. Jonathan
This par has periodicity=0, so the next statements don't matter.
Removing periodicity=0 doesn't seem to have any effect. I thought the periodicity setting would only be relevant if inside=per? This parset uses inside=bof61.
