VizieR Online Data Catalog: Ultra-diffuse & LSB dwarf galaxies in A370 from HFF (Lee+, 2020)

We obtained deep and high-resolution images of A370 from the Hubble Frontier Fields (HFF) archive (Lotz+ 2017ApJ...837...97L). We chose drizzled images of ACS/WFC F606W(V), F814W(I), WFC3/IR F105W(Y), and F160W(H) for our analysis. The HFF images we used cover two fields with different clustercentric distances (r/r200): the central field (r/r200<0.2) and the parallel field (r/r200~0.6-0.8) located at 5.9" southeast of the central field.

We adopt the ΛCDM cosmological parameters with H₀=73km/s/Mpc, Ω_M=0.27, and Ω_Λ=0.73. The luminosity distance of A370 for these parameters is d_L=1942Mpc, and the angular diameter distance is d_A=1028Mpc.
