345 GHz Observing Period from February 1 to 15

The IRAM 345 GHz SIS receiver was installed at the telescope on February 1 and 2, and it was available for antenna efficiency measurements and observations until February 15. The installation went smoothly without problems. See the Receiver section below for more details (page gif).

During the first week, few observations were possible due to bad weather, but in the second week, the receiver could be used during longer periods. The best zenith optical depth at 345 GHz was around 0.2 .

A detailed report about this 345 GHz observing period and antenna efficiency measurements is currently being prepared.
