Abstract

The luminosity function of the globular cluster Palomar 1 is determined together with its confidence interval by applying an adaptive kernel estimator to data from the Isaac Newton Telescope. The luminosity function of Palomar 1 has two minima in the V band and one in the I band. The cluster core contains a relatively high fraction of bright stars, indicative of mass segregation.
