Alan, I created a GINI with the identical garea you currently use for PROJ=STR/90;-105;0, Hopefully it matches the same sensor ID as the last one I sent you (we went around a couple of iterations to get the imgtyp.tbl correct). I've added a land use mask so that the great lakes and salton sea are better represented by land/water colors. I've attached both the gini as well as a gif for you to look at..
