The astronomical position-velocity data is from a sample of 26 low surfaces brightness (LSB) galaxies. The data contain 318 stars with their radiuses in kiloparsec (kpc), observed velocities of stars in km/s (relative to center, corrected for inclination) from 26 LSB galaxies. It was known that the velocities were measured with errors. In the data set, each velocity includes its estimated standard deviation of measurement errors.
A data frame with 318 observations on 3 variables.
