... As a result, the column of water vapour which normally blocks the transmission of electromagnetic waves from the near infrared through to the sub-millimetre waveband is very low at the surface, and is virtually absent at high altitude. ...
... The observations are best done at near-infrared wavelengths since these pass bands cover the wavelengths where the majority of ... Although current near-infrared imagers can reach upper-AGB stars in the nearer of the dEs within the Local Volume using ...
