The galaxy ESO121-G020

HIPASS J0615-57

RA, DEC(J2000) = 06:15:58, -57:44:29

Galactic l,b = 266.5, -27.3

S_peak = 0.210 +- 0.021 Jy

F_HI = 14.1 +- 2.9 Jy km/s

v_hel = 577 +- 5 km/s

w₅₀ = 65 km/s

w₂₀ = 96 km/s

v_LG = 311 km/s -> D_h75 = 6.1 Mpc

log MHI (Msun) = 7.76

no velocity was known for ESO121-G020 prior to the HIPASS measurements

we detected a small companion to ESO121-G020 in ATCA HI data which contributes to the HI flux density of HIPASS J0615-57
