Seeing

Atmospheric steadiness, using cloud, turbulence and low-level wind. Higher values mean sharper potential detail.

Transparency

Clarity through the full air column, influenced by atmospheric moisture. Higher values favour faint targets.

Pickering

Expected light distortion from turbulence, wind and temperature changes aloft. Higher values mean steadier stars.
