Clustering of Local Group distances: publication bias or correlated measurements? VII. A distance framework out to 100 Mpc

Understand

We consider the published distance moduli to the Fornax and Coma galaxy clusters, with emphasis on the period since 1990.

• We have carefully homogenized our catalogs of distance moduli onto the distance scale established in the previous papers in this series.
• We assessed systematic differences associated with the use of specific tracers, and discarded results based on application of the Tully--Fisher relation and of globular cluster and planetary nebula luminosity functions.
• We recommend `best' weighted relative distance moduli for the Fornax and Coma clusters with respect to the Virgo cluster of $\Delta (m-M)_0^{\rm Fornax - Virgo} = 0.18 \pm 0.28 $ mag and $\Delta (m-M)_0^{\rm Coma - Virgo} = 3.75 \pm 0.23$ mag.
