System Performance
- The SEQUOIA array is competitive with wideband SIS receivers, and much simpler to use.
- The receiver is cooled by a single 3.5W (at 18K) refrigerator.
- SEQUOIA's spectral line baseline stability is excellent. Gain fluctuations are large (0.2%) but highly correlated across a wide band.
- System reliability has been excellent in the first three years of operation.
