map projection

I am trying to plot data with the following projection information.
However, the data doesn't seem to correctly plot in the correct
position on the map. A clip of the related code is included below.
Any idea what might be wrong? Since I have 4 points specified
in the projection data, is mpLimitMode="Corners" correct to use,
since it only allows 2 points? I am also not entirely sure about
mpLambertMeridianF.

Thanks, Mike
