Samyang 14mm f2.8 AF Profile Edit help

Can anyone offer advice on editing a profile I have for the above lens in PS6.

I have installed it and tried , so far it seems OK except for the rather heavy vignette adjustment.

So my question is , which line in the profile do you edit to change the degree of lightening and darkening of the file

<stCamera:FocalLengthX>1.364942</stCamera:FocalLengthX>
<stCamera:FocalLengthY>1.364942</stCamera:FocalLengthY>
<stCamera:ImageXCenter>0.508561</stCamera:ImageXCenter>
<stCamera:ImageYCenter>0.499394</stCamera:ImageYCenter>
<stCamera:VignetteModelParam1>-6.351139</stCamera:VignetteModelParam1>
<stCamera:VignetteModelParam2>0.000000</stCamera:VignetteModelParam2>
<stCamera:VignetteModelParam3>0.000000</stCamera:VignetteModelParam3>
<stCamera

I am guessing it is the line " VignetteModeParam1>-6.351139

If so will reducing this figure reduce the degree of brightening in the corners ?

Gear ... what I need to get the job done , after all you don't see mechanics listing their brand of spanner as a qualification .
