NSA/MWRP/C1 - Radiometer in mixed scanning-zenith mode

After installing the spare radiometer (D080409.2), the data started to be intermittent and 
the software froze several times. To test if the problem was due to the scanning 
procedure used with the other radiometer, the instrument was run with a zenith-only procedure at 
times and with the usual scanning procedure at restart. When restarted with the scanning 
procedure the software had problems, so it was decided to run the spare instrument only 
with the zenith-viewing mode until our instrument comes back.

The quality of the data should be unaffected. The only difference is that only data 
collected at 90 degree angle will be available until our instrument comes back.
