Correlator chips:

A probation period on one unit of the Plateau de Bure correlator has demonstrated that the recently manufactured correlator chips are free of the failures experienced with the previous ones. The replacement of all the present chips has been considered and a reasonable compromise has been found with the manufacturer: 1254 new chips will be delivered by the end of June. All first generation chips will be replaced, both on Pico Veleta and Plateau de Bure. This operation is not urgent and may take place during maintenance or bad weather. Hopefully this will end the trouble.
