types are like this:
float4 - single precision 4-byte floating point
complex8 - single precision 8-byte complex number, composed of 4-byte real and imaginary parts in sequence.
float - real floating point number
complex - A complex number as a pair of floating point numbers, real part first.
Width - number of bytes used to store the entire number. For a complex number, the width is the sum of the width of two floating point numbers that compose it.
Some data objects are a single array, and some two arrays. There is always a Y array. If there are two arrays, there is either an f array or an t array, with the Y array appended.
