******************************************************************* 
Important Note for Observer:
The refurbishment work of the W02 antenna reflector surface is 
currently in progress. The refurbishment of the inner sectors 
will commence from 16th May 2023 onwards. Please note that this 
ongoing work may affect the sensitivity of the antenna and could 
also alter the primary beam pattern depending on the size of the
holes present on the surface. We advise exercising caution in 
using the antenna, particularly if your targets are extended or 
if you\'re using a wide field.
