Experiment Feedback

Onsala (Michael Lindvist at Mon Nov 3 21:42:12 2008) Success :

Had to put in attenuators for the 23.8 GHz part (due to the IF-slope). Otherwise no known problems.

Metsahovi (Metsahovi at Tue Nov 4 08:11:15 2008) Minor failures :

We had internal network problems and we could not connect mark5 to internal/external LAN. There we did not participate in the network tests.

Yebes (Pablo de Vicente at Tue Nov 4 09:38:24 2008) Failure : RECE

No fringes were detected. We suspect the problem was a faulty IF for our 22 GHz receiver. Symptoms were 12 dB less power at the output of the IF compared to previous 22 GHz observation and double Tsys for LCP compared to RCP. Mode 2 and 4 might be successful, since the IF seemed to behave differently then. We have sent an interval of data and are waiting for the correlator results.
