The ACSIS spectrometer is used with all the heterodyne instruments. The receivers are further described here:
- 350 GHz array receiver HARP,
- Three-receiver heterodyne instrument, Nāmakanui, is currently being commissioned. Nāmakanui was built by a team at ASIAA (Taiwan) and is on loan to the JCMT as a spare for the GLT. For further information about each cartridge:
