Properties of NGC 7252 and its tidal tails.
|Component||H I velocities||MH I||MH2||LB|
|(km s-1)||(109 M⊙)||(109 M⊙)||(109L⊙)|
Notes. The H I mass and velocities of the remnant refer to the so-called Western Loop (see Fig. A.1). Molecular masses are calculated assuming XCO = 2.0 × 1020 (cm-2/ K km s-1) and using the CO fluxes from Dupraz et al. (1990) and Braine et al. (2001). For the NWT the molecular mass is a lower limit because single-dish observations cover only a fraction of the tail. B-band luminosities are taken from Hibbard et al. (1994) and rescaled to a distance of 66.5 Mpc.
