e-MERLIN/VLBI National Facility


e-MERLIN requests proposals from the international astronomical community for observations to be made during Cycle-1. Proposals will be peer-reviewed by the e-MERLIN Time allocation Committee, following the procedures of the STFC Panel for Allocation of Telescope Time. Allocation will be made on the basis of scientific merit and technical feasibility alone. During this period approximately 50% of observing time is allocated to 12 large legacy projects and most of the remaining time will be allocated via PATT to standard proposals solicited prior to each observing semester.

e-MERLIN provides high resolution (40-150mas) and high sensitivity (~6-12 uJy in this Cycle-1) imaging at cm wavelengths as well as polarimetry, spectroscopy and astrometry. Cycle-1 observations will commence in September 2013, with some limitations in observing capabilities.

Developments during cycle-0 and cycle-1:
Throughout Cycle-0 extensive test and commissioning activity has been undertaken. During semester Cycle 1, a limited amount of continued commissioning and development work may still take place for some modes of operation. This essential system work will take priority over PATT observations. The continuum bandwidth at C-band is currently limited to 512MHz, and this should be assumed in proposal requests. The hardware for 2 GHz bandwidth operations is being tested now and is expected to be available at all telescopes in late 2013. PATT observations made after this development may benefit from this extra bandwidth once it becomes available, however this will be offered on a shared-risk basis initially. All proposals should be justified assuming the current available bandwidth of 512MHz.
