I don't know what you mean by that, these are the coordinates.
-- original function according to the wiki
radararea createRadarArea ( float leftX, float bottomY, float sizeX, float sizeY,
[ int r = 255, int g = 0, int b = 0, int a = 255,
element visibleTo = getRootElement() ] )
-- these are my parameters, only I didn't put them in variable, I used them directly as you can see on the previous post
leftX= 71.701171875,
bottomY = -2789.59765625
sizeX = 2924.03125
sizeY = 1937.36816406
255,0,0 = rgb colors and the last parameter is alpha
