[texhax] vertical space between sections and paragraph

[McAllaster, Douglas, CTR, OASD(HA)/TMA]

Folks,

This is my first post to texhax.

I see parskip as a way to control vertical space between paragraphs.
Is there a way to control the amount of vertical space 
between section headings and the subsequent paragraph?

Thx, Doug McAllaster
