LOFAR Technical Information


LOFAR, the Low frequency Array, is a next-generation electronically steered phased array radio telescope. LOFAR's capabilities are revolutionising the astronomical capabilities in the 10-240 MHz range.

These web pages describe the general signal path, major observing modes, and their post processing options from the perspective of the potential user.  In some instances, some modes are noted as being "Expert Mode": These are generally modes which require more manual intervention than the regular modes and are offered only to users who are familiar with them from their own commissioning work.  

A more detailed description of the LOFAR array can be found in van Haarlem et al. 2013 (http://arxiv.org/abs/1305.3550)
