Degausing AppleColor RGB?

[spector@vax2.concordia.ca (Mitchell Spector)]

	For the past few months, I've noticed what looks like a problem with
my current AppleColor RGB screen. If the screen background is set to all white,
I can see a bit of red on one side and blue on the other, the very center seems
to be pure white (red, white and blue distortions, could it be my GS thinks 
it's July 1st already? :-) Here is the way the distortion looks, it's strongest
on the far left and right sides:
   _______________
  |BBB  B   R  RRR|
  |BBBB  B R  RRRR|
  |BBBBB     RRRRR|
  |BBBB  B R  RRRR|
  |BBB__B___R__RRR|

B = Minor Blue distortion
R = Minor Red distortion
	
	I think the monitor needs some sort of degausing. The question is, how
do I go about fixing it? Is there a manual control that can fix this, or perhaps
something I else I could do (I vagely recall someone mentioning a weak magnetic
can fix this). I also noticed text and graphics expand outwards when inversed
(ie, selecting a paragraphic of text from ProTERM), but I think this is a side
effect of pushing up the master contrast (SUB-CONT) too high.
