Notes. The columns indicate which data points (meridional, superior, and inferior culmination) are fitted, which range of h was included in the fit, the intercept a and slope b of the fit, the rms of the differences between the data points and fit, the number of points n used in the fit, and nrej the number of points rejected because they lie more than 3 rms from the fitted line.
