Notes. Magnitudes and surface brightnesses are uncorrected for Galactic extinction.
a Apparent magnitude calculated by Equation Ltot = 2πI0rs2nΓ(2n), where I0 is the intensity at the center, rs is the scale length, and Γ is the gamma function.
b Color measured within twice the effective radius derived from R-band image.
c Central surface brightness (μ0,R), Sersic index (n), and effective radius (re) in the R-band image derived from the 1-D profile fit.
d Absolute magnitude calculated by assuming that the dwarfs are at the same distance as NGC 1291 (d = 9.08 Mpc).
e Stellar mass estimated with an equation of log M✭/L = 0.872×(B-R)-0.866 adopted from Into & Portinari (2013).
f Cross-ID: [MDS99] F301-056, [MDS99] F301-044, [MDS99] F301-064, LEDA 587327, respectively.
