8. Most of the observations were carried out in daytime. The JCMT dish is protected from direct solar heating and from wind buffeting by a Goretex membrane that is transparent to submillimeter wavelengths. Mechanical stability of the JCMT allows pointing to about ±1.5 arc sec root mean square over much of the sky.
