Post Question about the magnetic field strengths of stars.

This is for anyone who knows alot about stars. This is kind of a fill-in-the-blank deal. I've had difficulty finding the strengths of the magnetic fields of stars other than the Sun (25 gauss, I think it was) and pulsars (a trillion or more gauss). So could someone give these field strengths (a number range or average strength; whatever you prefer) for me?

MAIN SEQUENCE
O/B:
A:
F:
G: 25 gauss?
K:
M:

DWARF STARS
Red dwarf:
White dwarf:
Brown dwarf:

GIANTS/SUPERGIANTS
O/B:
A:
F:
G:
K:
M:
Hypergiants (Pistol Star, etc.):

Thanks.

I found quite a few numbers from a google search on...

magnetic field stellar gauss "main sequence"

Many astronomy journals are on line at the ADS - web search for "ADS" will find it.
