The metal-poor , fundamental-mode ( P0 ) and first-overtone ( P1 ) Cepheids in the dwarf galaxies IC 1613 , WLM , Pegasus , Sextans A , Sextans B , and Leo A are compared with the about equally metal-poor Cepheids of the Small Magellanic Cloud ( SMC ) .
The period-color ( P-C ) and period-luminosity ( P-L ) relations of the seven galaxies are indistinguishable , but differ distinctly from those in the Large Magellanic Cloud ( LMC ) and the solar neighborhood .
Adopting ( m - M ) ^ { 0 } _ { SMC } = 18.93 from independent evidence , one can determine reliable distance moduli for the other dwarf galaxies of ( m - M ) ^ { 0 } = 24.34 \pm 0.03 , 24.95 \pm 0.03 , 24.87 \pm 0.06 , 25.60 \pm 0.03 ( mean for Sextans A & B ) , and 24.59 \pm 0.03 , respectively .
