Auxiliary-data invariance conjecture for strongly invertible knots

Let KK be a strongly invertible knot in (S3,τ)(S^3,\tau), and let \fra\fra denote auxiliary data used to define its real knot Floer groups. Suppose that ι\iota is a periodic involution on the same underlying knot KK satisfying

ιτ=τι.\iota\circ\tau=\tau\circ\iota.

Auxiliary-data invariance conjecture. The auxiliary data \fra\fra does not affect the real knot Floer groups.

The conjecture is motivated by examples where real knot Floer homology depends on auxiliary data, together with a result concerning moving basepoints. The supplied text gives no resolution, so the extent of this invariance remains open.
