Oops, my mistake i mixed up the checks... it does indeed check for 1 element (a 4 bytes float).
 
	This is the struct for cell attributes in aegis, and the check against water level uses h1
 
struct AttrCell
{
	float h1;
	float h2;
	float h3;
	float h4;
	int flag;
};
	*Edit*: corrected the code in previous post
