The luminosity and mass function of the globular cluster NGC 1261.

ZOCCALI M., PIOTTO G., ZAGGIA S.R. and CAPACCIOLI M.

Abstract (from CDS):

I-band CCD images of two large regions of the Galactic globular cluster NGC 1261 have been used to construct stellar luminosity functions (LF) for 14000 stars in three annuli from 1.4' from the cluster center to the tidal radius. The LFs extend to MI∼8 and tend to steepen from the inner to the outer annulus, in agreement with the predictions of the multimass King-Michie model that we have calculated for this cluster. The LFs have been transformed into mass functions. Once corrected for mass segregation the global mass function of NGC 1261 has a slope x0=0.8±0.5
