Water and vegetable oil magnitude spectra measured with four interleaved echo trains and rBW 114 890 Hz. The spectra were measured and computed with (a) 16, (b) 32, (c) 64 and (d) 96 echoes. Corresponding spectral resolutions were (a) 0.61, (b) 0.31, (c) 0.15, and (d) 0.1 ppm. The ghost peaks of water and fat line (-CH₂-)_n are marked by *.
