... As higher frequencies (particularly 20 GHz) it is important to make corrections for atmospheric opacity and gain-elevation effects. ... This means that gain-elevation and opacity corrections will not work until a work around is implemented. Gain-elevation curves for some telescopes and frequencies are known to ASAP (currently only for Tidbinbilla at 20 GHz). ... Opacity corrections can be made with the global function opacity . ... ASAP opacity corrections should not be used for Mopra 3-mm data. ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...
