AbsorberTests - www.iram.es Main Wiki

Absorber tests are done on Mambo 1 and Mambo2 to measure the bolometer noise and possible anomouls noise (acceleration,reheating, ...)

How to proceed

Ideally the measurements should be done with the moving telescope to be as cloas as possible in the observation condition.

   > Pick-up a source  at the requested  elevation (see XEphem)
   pako> source G34.3 /grep /cat ihet
