abstract
Extragalactic Type II Cepheids are tentatively identified in photometric surveys of IC 1613, M33, M101, M106, M31, NGC 4603, and the SMC. Preliminary results suggest that Type II Cepheids may play an important role as standard candles, in constraining the effects of metallicity on Cepheid parameters, and in mapping extinction.

Evaluating Cepheid Metallicity Effect Determinations via IC1613 and Gaia-independent Parallaxes
Unifies HST parallaxes to obtain IC1613 distance ~24.39 mag and disfavors large Cepheid metallicity corrections γ(W_VI) of -0.25 or -0.50 mag dex⁻¹ relative to TRGB benchmarks.
