Abstract | H iline profiles, together with derived redshifts and integral properties, are presented for 46 Scd galaxies. The profile shapes are quite regular, with a double-peaked structure characteristic of galaxies with flat rotation curves. The ratios Ma 1/MT and MHi/Lpg, which are known to vary with Rubble type, have observed dispersions of I 80 percent within this classification, with intrinsic dispersions being probably l ... |
