EROS and MACHO Combined Limits on Planetary Mass Dark Matter in the   Galactic Halo
  The EROS and MACHO collaborations have each published upper limits on the amount of planetary mass dark matter in the Galactic Halo obtained from gravitational microlensing searches. In this paper the two limits are combined to give a much stronger constraint on the abundance of low mass MACHOs.
